For a server configured to save its password, entering a rotated password at the reconnect/password-prompt dialog appeared to work for the current connection but never replaced the stale saved ciphertext, causing an infinite re-prompt loop on every subsequent connection (e.g. opening the Query Tool).

Three gaps caused this:

  1. Query Tool's "already connected" reconnect path (sqleditor.connect_server) cached the freshly entered password on the in-memory server manager only, never writing it back to the stored server record.
  2. The password-prompt dialog always defaulted its "Save Password" checkbox to unchecked and only reported its own state, so a server already configured to save its password never got its stale ciphertext replaced.
  3. The driver's in-memory manager.password correction was never persisted via manager.update_session(). Driver.managers is an in-process cache, so in a multi-worker deployment (e.g. OpenShift/Helm) the next request can land on a different worker, which restores the stale pre-fix manager from the session.

Fix:

  • psycopg3/connection.py: call manager.update_session() right after manager._update_password() in connect(), so every connect path benefits.
  • sqleditor.connect_server: validate the entered password with a throwaway connection before caching or persisting it, then persist it to the owned or shared (SharedServer) record when Save Password is set and allowed. An explicit save_password=false clears the saved credential; a request that omits the field leaves it alone.
  • ConnectServerContent.jsx: seed the checkbox from the server's current save_password and send the field only when the server reported it or the user ticked the box, so prompts that don't report the state (e.g. ERD) can't trigger an opt-out. The ERD and Query Tool 428 responses now include save_password (the Query Tool ones read the record that will actually be updated, i.e. the user's SharedServer row for non-owners).
  • Roll back the session on a failed persist, and reuse _is_non_owner() / pgadmin.utils.str_to_bool.
  • Tests: owner/shared persist and clear, rollback on failure, password validation, opt-out vs. field-omitted handling, and a ConnectServerContent spec.

Walkthrough

Server connections now parse explicit save-password choices and expose the current setting in password prompts. Query Tool prompts validate passwords before caching and persist or clear credentials for owned and shared servers. Successful password corrections also update the manager session.

Changes

Saved password flow

Layer / File(s) Summary
Save-password state and connection handling
web/pgadmin/utils/__init__.py, web/pgadmin/browser/server_groups/servers/__init__.py, web/pgadmin/static/js/Dialogs/ConnectServerContent.jsx
str_to_bool parses save-password values. Prompts include the current setting, and the dialog submits the checkbox state on every request. Explicitly disabling password saving clears stored credentials.
Query Tool password persistence
web/pgadmin/tools/sqleditor/__init__.py, web/pgadmin/tools/sqleditor/tests/*, web/pgadmin/tools/sqleditor/utils/tests/test_cache_manager_password.py
Query Tool prompts validate passwords before caching them. Requested credentials are persisted or cleared for owned and shared server records. Tests cover routing, rollback, validation, and boolean parsing.
Manager session correction
web/pgadmin/utils/driver/psycopg3/connection.py
After a successful password update, the connection path updates the manager session.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: dpage

Merge Risk: Minimal · previous review cba82

The password prompts now preserve the saved-password choice and persist validated replacements. No actionable merge-blocking regression was established; the existing shared-server import issue remains separate from this change.

Security architecture risk: Low · up to cba82

The change improves password validation and reconnect recovery. Two bounded credential-retention concerns remain: a shared-server prompt can use the owner's saving preference instead of the caller's, and a failed save or clear can still return connection success. The inspected persistence paths retain per-user ownership checks.

Retained concerns

  • Low · security · observed: The View/Edit Data password prompt newly reports the owner's Server.save_password value rather than the caller's per-user SharedServer setting. The dialog uses that value to initialize and submit its saving choice. When owner and caller preferences differ, the prompt misrepresents the caller's credential-retention state and can produce an unintended save or clear request. The main connection and Query Tool initialization flows apply the per-user overlay, limiting this concern to the inconsistent prompt producer.
  • Low · security · observed: The already-connected reconnect path updates manager/session credentials before attempting the new durable save or clear operation. A database failure rolls back that operation, but the outer helper logs and swallows the exception and the endpoint still returns success. An explicit opt-out can therefore leave the encrypted saved credential retained without reporting that the retention change failed. This extends an existing best-effort cache handler to a security-relevant durable-state transition.
Security review details

Security Blast Radius

  • observed — The reconnect endpoint requires authentication and an accessible server ID. In server mode, accessible records include the caller's servers and servers marked shared. New durable writes select the caller-owned Server or the current user's SharedServer; the identified concerns affect that user's credential-retention state rather than demonstrating cross-owner write authority.

Security Findings and Attack Paths

  • inferred — A user submitting a valid replacement password and an explicit saving opt-out can receive connection success even when the clear transaction fails. The prior saved ciphertext then remains retained. This outcome requires a persistence failure; no attacker capability to induce that failure or obtain the ciphertext was established.

Trust Boundaries and Controls

  • observed — Server access and per-user persistence routing are separate controls. The shared-record lookup is keyed by current_user.id and server ID, and failure to obtain that record raises rather than returning an owner record. Password validation protects the new persistence sink from invalid submitted credentials, while the prompt's saving preference must also be sourced from the correct user's state.

Resilience and Maintainability Implications

  • observed — The main connection path releases its connection and returns an error on durable save/clear failure. The already-connected path instead preserves connection availability by swallowing the same class of failure. This difference matters when connection availability is mistaken for successful credential-retention control.

Hardening Proposals

  • proposed — Keep saving preferences user-scoped across every prompt producer, distinguish connection success from durable credential-change success, and define recovery and ordering for concurrent save/clear transitions.

I traced this one carefully because it touches stored credentials. Good news first: there's no cross-user leak. get_shared_server_properties() (servers/__init__.py:170-234) overlays the caller's own SharedServer row and expunges the owner's Server from the session, so save_password is read from the caller's row and the write lands on shared_server. The right encryption key is used (get_crypt_key(), the current user's), nothing is written or logged in plaintext, and manager.update_session() stores the encrypted form, not the raw password.

That said, I don't think this is mergeable yet.

1. The main fix doesn't actually fix the described bug (servers/__init__.py:1775) — and is redundant when it does run.
The new if password: manager.update_session(). Here's the sequence:

  • Connection.connect() → _initialize() → _set_server_type_and_password() sets manager.password = kwargs['password']
  • _initialize then already calls manager.update_session() at connection.py:624
  • only after that does connection.py:422 run manager._update_password(encpass) — the correction that never gets persisted

That correction differs from what's already in the session only when kwargs['password'] was falsy, i.e. when encpass came from the self.password or getattr(manager, 'password', None) fallback at connection.py:299. And in exactly that case the new guard if password: is False, so update_session() is never reached. When password is truthy, line 624 already wrote the same value.

The fix belongs one level down, in the driver: make connection.py:422-423 read manager._update_password(encpass); manager.update_session(). That repairs every caller — sqleditor, backup, debugger, schema diff — instead of just ServerNode.connect, and the hunk at 1775 can go.

2. A wrong password now gets saved permanently (tools/sqleditor/__init__.py:2780-2797).
_persist_saved_password writes to durable storage without ever checking the password against the server. connect_server only reaches this code because conn.connected() is already True (line 2704) from a connection that existed beforehand — the password the user just typed is never used in a conn.connect(). So a typo at the prompt overwrites a working stored credential, and every connection after that fails until the user notices and fixes it by hand. Compare ServerNode.connect, which persists only inside the post-conn.connect() success branch. Please validate first (throwaway connection with the supplied password), or defer persisting until the next real connect.

3. Unchecking "Save Password" no longer works (servers/__init__.py:1694-1697).
The or bool(server.save_password) overrides an explicit user choice. ConnectServerContent.jsx:29 defaults save_password to false and :122-123 only appends the field when it's true — so the backend genuinely cannot tell "the user unticked the box" apart from "the dialog didn't send the field". Result: someone who deliberately unticks Save Password on a save-enabled server gets it saved anyway. This can't be repaired server-side; the dialog has to seed the checkbox from the server's current setting (the 401/428 payload already carries allow_save_password at ConnectServerContent.jsx:101 — add save_password) and always send the field.

4. No tests. gh pr diff --name-only shows two source files and no test file, on a change that alters when a credential is written and which row it lands on. connect_server has no coverage at all today. At minimum: a server-mode test asserting a non-owner's rotated password lands on their SharedServer row and leaves the owner's Server.password untouched, plus one for save_password=0.

Smaller items:

  • :2797 — db.session.commit() with no rollback() on failure; the outer except at 2776 swallows the error and leaves the session pending-rollback for the rest of the request.
  • :2773 — the truthiness list ('true', 'True', '1', 1, True) misses 'TRUE', 'on', 'yes'. str(save_password).lower() in ('true', '1', 'on', 'yes') is safer.
  • :2788-2796 — reimplements _is_non_owner() (servers/__init__.py:62-65) and the owner/shared branch inline. Import and reuse it; two copies of a credential-routing rule will drift apart.

kundansable added a commit to kundansable/pgadmin4 that referenced this pull request Sep 7, 2026
- Move the manager.update_session() call for a corrected password into
  the driver's connect() (right after manager._update_password()) so
  every connect path benefits, not just ServerNode.connect. Drops the
  redundant/ineffective call that was added there.
- Query Tool's reconnect path never uses the freshly typed password to
  open a real connection, so validate it against the server (via a
  throwaway connection) before persisting it -- a typo at the prompt
  must not silently overwrite a working saved password.
- Seed the "Save Password" checkbox from the server's current setting
  and always send its state, so the backend can tell "explicitly
  unchecked" apart from "field not sent" and stops overriding an
  explicit uncheck.
- Roll back the session on a failed password-persist commit, reuse
  _is_non_owner() instead of a duplicate inline check, and consolidate
  boolean-ish request field parsing into pgadmin.utils.str_to_bool.
- Add unit tests for the owner/shared routing, rollback-on-failure, and
  password validation/boolean-parsing helpers.

Return the current save-password state in the Query Tool prompt.

This 428 payload omits save_password. ConnectServerContent therefore initializes the checkbox to false. For a server with a rotated saved password, the Query Tool prompt submits false and lines 2777-2780 do not persist the validated replacement. This leaves the stale database credential in place.

Add "save_password": bool(server.save_password) to this response payload.

Comment thread web/pgadmin/tools/sqleditor/__init__.py Resolved
For a server configured to save its password, entering a rotated
password at the reconnect/password-prompt dialog appeared to work
for the current connection but never actually replaced the stale
saved ciphertext, causing an infinite re-prompt loop on every
subsequent connection (e.g. opening the Query Tool).

Two gaps caused this:

1. Query Tool's "already connected" reconnect path
   (sqleditor.connect_server) cached the freshly entered password on
   the in-memory server manager only, never writing it back to the
   stored server record.

2. The main "Connect to Server" flow (ServerNode.connect()) only
   persisted a freshly entered password to the server's stored
   ciphertext when the current request's save_password flag was
   true. But the password-prompt dialog shown on a failed connect
   doesn't resend the server's existing save_password setting -- it
   only reports its own checkbox state, which defaults to
   unchecked -- so a server already configured to save its password
   never got its stale ciphertext replaced. Separately, the driver's
   in-memory manager.password fix was never persisted via
   manager.update_session(); Driver.managers is an in-process cache,
   so in a multi-worker deployment (e.g. OpenShift/Helm) the next
   request can land on a different worker, which restores the stale
   pre-fix manager from the session and loses the corrected
   password.

Fix all three: persist the new password to the (owned or shared)
server record from the Query Tool reconnect path when save_password
is set and allowed; treat save_password as true in the main connect
flow whenever the server already has it enabled, not just when the
current request's flag says so; and call manager.update_session()
after a successful connect that used a freshly entered password.

Addresses review comments on PR pgadmin-org#10178.
- Include save_password in the Query Tool's own 428 password-prompt
  payloads (initialize_viewdata, _init_sqleditor) so the dialog seeds
  its checkbox correctly there too, not just from ServerNode.connect.
- Clear a server's stored save_password/password when the user
  explicitly submits save_password=false for a server that had one
  saved, instead of only ever handling the "save" case. A new
  save_password_provided flag keeps legacy callers that omit the field
  from having a saved credential wiped out.
- Validate the reconnect-path password before caching it on the
  manager/session at all, not just before persisting it to the DB --
  a typo must not replace a working in-memory/session password either.
- Fix pycodestyle E123 in the new test file by switching stacked
  `with` clauses to nested `with` blocks.

Validate the password against the Query Tool target.

connect_server() calls _password_is_valid() with manager.db (server.maintenance_db) and manager.user. _init_sqleditor() can connect with a different dbname or did, and _connect() can use a requested user. Validation can therefore reject a password that works for the Query Tool connection, preventing caching and persistence. Validate against the selected database and user.

TestStrToBool verifies parsing only. Add request-level tests for _cache_manager_password_from_request with an explicit false value. Assert that owned and non-owner shared records clear both save_password and password. This protects the stale-password regression fixed by this PR.

_cache_manager_password_from_request now validates the entered password
against the server before caching it, so the test must stub
_password_is_valid. Add a scenario for a rejected password.

@coderabbitai re the 'Validate the password against the Query Tool target' finding in #10178 (review): this is intentional. The value is cached on the manager and saved as the server's credential, which is used as manager.user, so that is the identity it must authenticate as.

@dpage Thanks for clarifying. The password is cached on the manager and saved as the server credential, so validation must authenticate as manager.user, not as the Query Tool target’s user. My finding assumed the wrong credential scope. I withdraw that finding.

Learning: In pgAdmin's Query Tool reconnect flow in web/pgadmin/tools/sqleditor/__init__.py, the supplied password is cached on the manager and saved as the server credential. Password validation must authenticate as manager.user, even when the Query Tool target uses a different user. Do not require validation as the Query Tool target's user for this server credential.

Thanks for working through Ashesh's review; the driver-level update_session(), the validation before caching and the tests all look good. There's one regression I'd like fixed before this goes in, plus a few smaller things.

1. A prompt that doesn't report save_password now clears a saved password.

ConnectServerContent now seeds the checkbox from data.save_password and always posts save_password, even when false. That works for the prompts that include the field (the browser's connect response and the two in sqleditor/__init__.py), but the ERD tool's 428 response (tools/erd/__init__.py, around line 612) doesn't include it. There the checkbox starts unticked, ERDTool posts save_password=false to sqleditor.connect_server, and once the entered password validates, _cache_manager_password_from_request treats that as an explicit opt-out and calls _clear_saved_password(). So simply entering a password at an ERD prompt deletes the user's saved password, which is the opposite of what this PR is for.

Please fix it on the client, so that every current and future caller is covered, by only sending the field when the server told the dialog its state or the user ticked the box:

if (data.save_password !== undefined || formData.save_password) {
  postFormData.append('save_password', formData.save_password);
}

Adding "save_password" to the ERD response as well would make the checkbox show the right state there too. ConnectServerContent is also used by Schema Diff, the Workspaces ad-hoc connection dialog and the Query Tool's new connection dialog, so please check that each of those either supplies save_password or is covered by the guard above.

2. Tests for the explicit opt-out. Nothing exercises _clear_saved_password() or the explicit-false branch. Please add request-level tests asserting that posting save_password=false with a valid password clears save_password and password on both an owned server and a non-owner's SharedServer row, and that a request without the field leaves a saved password alone (which would have caught the issue above).

3. Shared servers (minor). get_server() returns the owner's Server row, so for a non-owner of a shared server, the new "save_password": bool(server.save_password) in initialize_viewdata and _init_sqleditor reflects the owner's setting rather than the current user's. Using _get_save_password_target(server).save_password there would make the checkbox match the record that will actually be updated.

4. PR description. Point 2 still says the backend treats save_password as true whenever the server already has it enabled, which was replaced by seeding the checkbox in the dialog. Please bring the description up to date, and reply to Ashesh's review so he knows it's ready for another look.

- ConnectServerContent only posts save_password when the server reported
  the current setting or the user ticked the box, so a prompt that
  doesn't know the state (e.g. ERD) can no longer trigger an opt-out.
- Report save_password in the ERD 428 response.
- Seed the Query Tool prompts' save_password from the record that will
  actually be updated (the user's SharedServer row for non-owners).
- Add tests for the explicit opt-out (owned and shared) and for the
  field-omitted case, plus a ConnectServerContent spec.

Thanks both. @dpage's review is addressed in 15a6a0e (CI is green):

  • Opt-out regression: ConnectServerContent now sends save_password only when the server reported it or the user ticked the box, so prompts that don't know the state can't clear a saved password. The ERD 428 response now reports save_password too.
  • Tests: added coverage for _clear_saved_password (owned and shared row), for save_password false/true/omitted in _cache_manager_password_from_request, and a ConnectServerContent spec.
  • Shared servers: the Query Tool prompts now read save_password from _get_save_password_target(server).
  • Description: updated to match.

@asheshv your earlier points (driver-level update_session(), validating before caching/persisting, seeding the checkbox, rollback, reuse of _is_non_owner/str_to_bool, tests) are covered as well. Ready for another look.

Merged current master into this branch to clear the conflicts. They were in the import block of servers/__init__.py and in sqleditor/__init__.py, where master added _connects_as_server_user(); I kept both. @dpage's 14 Oct points are addressed in 15a6a0e: the ERD prompt now reports save_password and the client only sends the field when it was reported or ticked, tests cover the explicit opt-out, shared servers read their own row, and the description is updated. @dpage @asheshv, could you take another look when you have a moment?

Extra verification on current master (d9647f93f) versus this branch (8990c41fb, master merged in).

Setup: server mode, PostgreSQL 18 with SCRAM auth, a server saved with its password, then the role's password rotated so the saved one is stale. I then posted the new password with save_password=true to sqleditor.connect_server, the same call the Query Tool prompt makes, and compared the server's saved password in the config database before and after.

master this branch
Saved password updated in the config DB no, the stale ciphertext stays yes

So on master the entered password is only cached for the session, and the next reconnect uses the stale saved one and prompts again, which is the loop in #10128. With this branch the saved password is replaced.

This exercises the mechanism through the REST endpoint, not the full Query Tool UI flow from the issue.

Thanks for the update, and for the end-to-end check. Everything from my last review is sorted: the ERD prompt and the client guard, the shared-server row, the opt-out tests and the description. Ashesh's points look covered too.

One thing I'd like changed before this goes in:

A disabled "Save Password" checkbox can now save the password. ConnectServerContent seeds the checkbox from data.save_password even when data.allow_save_password is false, so it shows ticked but disabled and posts save_password=true. Neither ServerNode.connect nor _cache_manager_password_from_request checks the session's allow_save_password, so the password gets saved. That flag is false in server mode with OAuth2/Kerberos/webserver auth and no master password, where the encryption key only lasts for the session; the newly saved password then can't be decrypted at the next login, which is the problem in #10140/#10174. Could you seed the checkbox as Boolean(data?.allow_save_password && data?.save_password) and only send save_password when data.allow_save_password is true? A session.get('allow_save_password') check before _persist_saved_password() would be a nice extra safeguard.

Two small ones:

  • The comment in ServerNode.connect around line 1913 still says the dialog "always sends its state". Since your last change it only sends it when the server reported it or the box was ticked, so it's worth rewording.
  • In TestPersistSavedPasswordSharedNonOwner, assertNotEqual(owner_server.password, b'enc-pwd') always passes on a MagicMock. Giving owner_server a real password=b'owner-enc' and asserting it's unchanged, as the clear test does, would make it check something.
