Release notes

Sourced from handlebars's releases.

v4.7.10

• security: Sanitize the source map URL when minifying - f37c599
• security: Iterate lazily in #each and strip whitespace in linear time - 812c226
• security: Escape <!-- and <script in precompiled output - 609d1b1 GHSA-xw65-4hp5-5hc7
• security: Don't trust special properties on context data - ceec388 GHSA-p8wg-vrv2-v86f
• security: Only compile partials that are template strings - c28ee7a
• security: Only dispatch known node types in the Compiler and Visitor - 7d501a5
• security: Validate AST values in the compiler instead of the parser - 703fdcc GHSA-8r5x-fm3f-whwj
• Clarify that --root does not restrict filesystem access - 0fcf25c
• Bump minimist to ^1.2.8 - ea8ed82

Dependabot Review: handlebars 4.7.10

Package Changes

Package	Change	Bump	Dependency type
handlebars	4.7.9 → 4.7.10	patch	transitive (dev)

Supply-Chain Verification ✅

Every package version that is new in package-lock.json (compared with merge-base e0f2915):

Package	Version	Scope	npm publish (UTC)	Publisher	Evidence	Result
handlebars	4.7.10	dev	2026-10-05 22:37:37Z	jaylinski	No provenance. Published by jaylinski, the same account as 4.7.9. The gitHead is tag v4.7.10, an unsigned commit with the git author handlebars-lang (no linked GitHub account), 8 min before the npm publish. jaylinski published the release 30 min after the npm publish. 43 files are identical to the tag, including the main entry lib/index.js, which loads dist/cjs/. The 74 dist/ files and the generated parser lib/handlebars/compiler/parser.js were not rebuilt.	✅

• The resolved URL and integrity hash of each new lockfile entry match the registry metadata.
• All other packages resolve the same dependency versions as before.
• No new entry has an install script.
• The diff changes only package-lock.json. The only commit is by dependabot[bot].

CI Status ✅

All 6 checks pass on head 9f71d63: Lint commits, Lint code, Run tests (20.x), Run tests (22.x), Run tests (24.x), Test coverage. Skipped: Release.

Breaking Changes / Impact

• handlebars 4.7.10 fixes GHSA-xw65-4hp5-5hc7 (medium), GHSA-8r5x-fm3f-whwj (critical) and GHSA-p8wg-vrv2-v86f (critical). {{#each}} now iterates Map, Set and generators lazily.
• Dev only, through conventional-changelog-writer.

Approved. Dev only. The handlebars 4.7.10 source files match the tag. This review did not rebuild the build files. The diff changes only dependency files. CI is green.
