build(deps-dev): bump js-yaml from 4.1.1 to 4.3.0 in /dashboard

[dependabot]

Bumps js-yaml from 4.1.1 to 4.3.0.

Changelog

Sourced from js-yaml's changelog.

4.3.0 - 2026-06-27

Added

• [backport] Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.

Fixed

• Restore umd builds back to es5.

Removed

• [backport] maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

[4.2.0] - 2026-06-01

Added

• Added docs/safety.md with notes about processing untrusted YAML.
• Added maxDepth (100) loader option. Not a problem, but gives a better exception instead of RangeError on stack overflow.
• Added maxMergeSeqLength (20) loader option. Not a problem after merge fix, but an additional restriction for safety.
• Added sourcemaps to dist/ builds.

Changed

• Stop resolving numbers with underscores as numeric scalars, #627.
• Switched dev toolchains to Vite / neostandard.
• Updated demo.
• Reorganized tests.
• dist/ files are no longer kept in the repository.

Fixed

• Fix parsing of properties on the first implicit block mapping key, #62.
• Fix trailing whitespace handling when folding flow scalar lines, #307.
• Reject top-level block scalars without content indentation, #280.
• Ensure numbers survive round-trip, #737.
• Fix test coverage for issue #221.
• Fix flow scalar trailing whitespace folding, #307.
• Fix digits in YAML named tag handles.

Security

• Fix potential DoS via quadratic complexity in merge - deduplicate repeated elements (makes sense for malformed files > 10K).

[3.14.2] - 2025-11-15

Security

• Backported v4.1.1 fix to v3

Executive Summary

This is a Dependabot bump of the transitive devDependency js-yaml (used by eslint via @eslint/eslintrc) from 4.1.1 to 4.3.0. Only dashboard/package-lock.json changed (+13/-3 lines). The bump brings important security fixes: a DoS fix via quadratic complexity in YAML merge (4.2.0), maxDepth safety option, and maxTotalMergeKeys limit (4.3.0). No breaking changes. Build passes, TypeScript compiles, lockfile is consistent.

Detailed Analysis

Security impact (positive):

• 4.1.1 to 4.2.0: Fixes potential DoS via quadratic complexity in YAML merge (<<) operator. Adds maxDepth (100) loader option. Adds docs/safety.md.
• 4.2.0 to 4.3.0: Backports maxTotalMergeKeys (10000) to limit total keys processed by YAML merge. Restores UMD builds to ES5.

Dependency chain: This is a transitive devDependency. js-yaml is pulled in by @eslint/eslintrc (which declares "js-yaml": "^4.1.1"). It is only used at dev/lint time, never in production builds. Risk of runtime impact: zero.

Lockfile integrity: Verified via npm install --package-lock-only --dry-run. The integrity hash matches.

Suggestions

1. [INFO] Consider adding js-yaml to devDependencies in dashboard/package.json if you want Dependabot to manage it directly. Currently it is only a transitive dependency.
2. [INFO] The eslint lint command (npm run lint) fails with a circular JSON error in @eslint/eslintrc config validation. This is a pre-existing issue unrelated to this bump.
