fix(deps): patch js-yaml and svgo audit advisories

[cristim]

The frontend lockfile on main causes Security Scanning to fail on new js-yaml and SVGO advisories. Update js-yaml to 3.15.2/4.3.2 and SVGO to 4.1.0 within existing parent ranges, including SVGO's required css-select 6/css-what 7 dependencies. Preserve package.json, application code and the full-tree audit gate.

Enable CodeRabbit review of npm lockfiles because its default filters skipped the dependency diff. The rule uses the exact positive inverse of the default npm-lockfile exclusion, **/package-lock.json; a literal frontend path was recognized but still skipped in the hosted run. The repository has two tracked npm lockfiles, in frontend and the server-json validator. Other default exclusions are not changed. Hosted file selection must be verified before merge.

Local validation on native macOS Node 26.8.1: audit reproduced two high-severity packages before and zero vulnerabilities after; fresh npm ci --ignore-scripts succeeded; production webpack build passed; Jest 90 suites and 2890 tests passed (one skipped); typecheck passed; lint passed with 125 existing warnings. All five changed package entries match registry integrity hashes. The review-only configuration was parsed and validated against CodeRabbit's official schema.

Merge gates: applicable local verification, passing CI at the final HEAD, a substantive clean CodeRabbit review covering the lockfile, and an independent adversarial review of the full final diff by a fresh-context gpt-6-astra agent, as requested by the user on September 11. Exact-head verdicts and CI results are recorded in the PR comments; green bot status without actual file coverage does not satisfy review.

Closes #2089

User-authorized reviewer change (2026-09-11): fresh-context Astra replaces the previous Opus/Fable requirement. Spawn metadata: model gpt-6-astra, reasoning high, fork_turns="none", agent /root/astra_fresh_review_2090. The reviewer received the issue, repository and exact base/head, but no implementer conclusions or earlier clean verdicts. Review was read-only.

Verbatim reviewer verdict:

NO CONFIRMED FINDINGS

Reviewer: gpt-6-astra, fresh-context agent /root/astra_fresh_review_2090.

Reviewed SHA: 27514811216736f0c484b55eaf8c5b823512a092 against base eac9a62a88d49cbb30abf1dc3943037dd1d58b0b. Local HEAD and live PR matched; worktree remained clean.

Full changed-file set: frontend/package-lock.json, 32 additions and 19 deletions. Reviewed all changes against issue #2089.

Checks and attacks completed:

• Verified all five changed package entries against npm registry metadata, including versions, dependency maps, engines, URLs and integrity values. Downloaded tarballs into memory and independently verified every SHA-512 checksum.
• Checked every incoming parent range and outgoing dependency of the changed entries. All resolved versions satisfy their ranges, including SVGO’s selector dependencies and exact sax@1.6.1 requirement.
• Submitted complete base and HEAD dependency inventories to npm’s bulk advisory endpoint. Base returned the specified js-yaml and SVGO vulnerabilities; HEAD returned {}.
• Confirmed patched versions against the js-yaml advisory, SVGO executable-link advisory, and SVGO foreignObject advisory.
• Verified installed versions match the reviewed lockfile. In-memory smoke checks passed for both YAML release lines: ordinary merges work, and empty merge sources hit the configured budget.
• Exercised SVGO with namespace-prefixed links, control characters inside executable URL schemes, and foreignObject event/srcdoc/action payloads. The dangerous attributes were removed.
• Exercised the actual cssnano → postcss-svgo → SVGO consumer chain with an SVG CSS data URI. Optimization succeeded.
• Confirmed package.json, application code and the full-tree npm audit --audit-level=high gate are unchanged.

Limitations: No fresh installation, full production build or Jest run, as instructed. The bulk advisory check is independent registry evidence, not an execution of npm’s audit CLI. Existing installed packages supplied the smoke checks. This verdict covers only the SHA above, not any subsequent CodeRabbit configuration change.

Root evidence captured this turn:

git rev-parse HEAD
27514811216736f0c484b55eaf8c5b823512a092
git status --porcelain
(empty output)
git diff --name-only eac9a62a88d49cbb30abf1dc3943037dd1d58b0b...HEAD
frontend/package-lock.json

All exact-head CI checks passed. A fresh local npm audit --audit-level=high --json also returned exit 0 with zero vulnerabilities. CodeRabbit skipped the lockfile under its default filters, so this PR is not yet merge-ready. A narrow include-rule correction is being prepared; any new HEAD will receive a new fresh-context Astra review and CodeRabbit review before merge.

[cristim]

Added .coderabbit.yaml in bf269e218e7ba55714047b84d182eb6e065c2373 to explicitly include frontend/package-lock.json. The previous review was skipped because the sole changed file matched CodeRabbit's default lockfile exclusion.

CodeRabbit documents positive path filters overriding default exclusions and including files that match no exclusion by default. The configuration adds only the exact lockfile path, with no broad pattern or additional exclusion.

Validation: parsed the actual YAML with existing js-yaml, asserted the exact three-line configuration shape, and validated it against the full official draft2020-12 schema using existing Ajv2020. Normal commit hooks passed, including YAML, secrets and Trivy checks. No dependency or application code changed in this follow-up. Fresh CI and substantive CodeRabbit review on this new HEAD remain required.

Base: eac9a62a88d49cbb30abf1dc3943037dd1d58b0b

Reviewed the complete changes in .coderabbit.yaml and frontend/package-lock.json, the only changed files. Independently read issue #2089 for acceptance criteria. No earlier reviewer verdicts, PR comments, implementer plans, or handoff conclusions were consulted.

Attacks and results:

• Lockfile consistency: exactly five package entries changed or were added, with none removed. Root dependencies match package.json semantically. Every affected consumer range accepts its resolved version. Apparent brace-expansion range mismatches were refuted by the unchanged manifest override.
• Registry integrity: all five entries match live npm registry tarball URLs, SHA-512 integrity values, and dependency metadata. Independently downloaded and hashed their tarballs in memory; every hash matched.
• Advisory coverage: submitted both complete lockfile inventories, including development dependencies and 738 unique package names, to npm’s bulk advisory endpoint. Base returned the three specified GHSAs; HEAD returned no advisories.
• YAML regression: reproduced 10,100 empty-source merge operations bypassing a budget of one in base versions 3.15.1 and 4.3.1. Patched versions reject excessive work. Zero/one budget boundaries, populated-source charging, ordinary merges, and explicitly unlimited operation passed.
• SVGO regression: reproduced namespace/control-character executable links and foreignObject srcdoc surviving base 4.0.2. Patched 4.1.0 passed probes for prefixed anchors, tab/LF/CR obfuscation, scripts, foreignObject event attributes, srcdoc, and executable HTML URL attributes. Benign links and visual content remained.
• Consumer paths: confirmed ESLint resolves js-yaml 4.3.2, Istanbul resolves 3.15.2, and postcss-svgo resolves SVGO 4.1.0. Exercised the cssnano default preset through postcss-svgo using CSS containing an SVG data URI and a style selector: successful optimization, no warnings.
• CodeRabbit configuration: validation against its published draft-2020 schema passed. The candidate finding that the positive lockfile filter excludes ordinary source was refuted by the official documentation: explicit includes override default exclusions. The exact path does not broadly include other generated content. Path-filter documentation, published schema.
• Scope: package.json, application code, and the full-tree npm audit --audit-level=high gate remain unchanged.

Limitations: no installation, production build, Jest suite, browser exercise, or hosted CodeRabbit execution was performed. Advisory verification used npm’s bulk endpoint rather than the npm audit CLI. Local probes used existing dependencies under Node 26.8.1; frontend CI specifies Node 24. Base SVGO’s bundle was evaluated with existing selector dependencies, sufficient to reproduce the sanitizer failures but not a complete base installation.

Final verification reconfirmed the exact HEAD, a clean worktree, the same two-file diff, and no git diff --check errors. No repository or GitHub mutations were made.

[cristim]

Corrected the path filter in 3f74875049e191c7c27e829b50fc78c346807ba0 to quoted **/package-lock.json, the exact inverse of CodeRabbit's default !**/package-lock.json exclusion.

The previous literal path was schema-valid but did not work in the hosted service: run 6b095550-1671-4552-91d6-8821d0824906 loaded .coderabbit.yaml and still reported the frontend lockfile both included and excluded. It also skipped the configuration file. That result supersedes the earlier interpretation of the documentation.

The bot's own guidance describes removing an explicitly overridden default pattern from both lists. This correction tests that exact-pattern behavior. It covers both tracked npm lockfiles, frontend/package-lock.json and .github/scripts/server-json-validator/package-lock.json, plus future npm lockfiles; other default exclusions are unchanged.

The actual YAML parses, its exact configuration shape was asserted, and full official schema validation passed using existing tooling. Normal commit hooks passed. No application or dependency changes in this follow-up. Fresh CI and substantive hosted review of this HEAD remain mandatory; validation alone is not proof of review selection.

Local verification at 3f74875049e191c7c27e829b50fc78c346807ba0, native macOS Node v26.8.1:

• Fresh npm audit --audit-level=high --json returned exit0, vulnerabilities: {}, and total vulnerabilities0 across895 dependencies (development dependencies included).
• git diff --exit-code 27514811216736f0c484b55eaf8c5b823512a092 3f74875049e191c7c27e829b50fc78c346807ba0 -- frontend/package-lock.json frontend/package.json frontend/src .github/workflows returned exit0 with no diff. The previously verified dependency lockfile, application code and workflows are unchanged by both review-configuration commits.
• Existing local installation/build/Jest/typecheck/lint evidence therefore covers unchanged frontend bytes. No claim that those complete suites were rerun for a configuration-only edit.
• The current YAML shape and official schema passed locally. Hosted CodeRabbit consumption remains a separate required check, not inferred from schema validation.

These are terminal-output excerpts, not a preserved full raw audit transcript. Tool results: audit f9d4be, Node db0522, identity comparison aa3b03.

Complete changed-file scope:

• .coderabbit.yaml
• frontend/package-lock.json

I independently read issue #2089 and inspected the complete diff without consulting previous verdicts, implementer plans, handoffs, or PR comments.

Attacks and results:

• Dependency consistency: all 21 relevant consumer and changed-package dependency edges satisfy their declared ranges. The only changed package records are js-yaml 3.15.2 and 4.3.2, SVGO 4.1.0, and its required css-select 6.0.0 / css-what 7.0.0 dependencies. Package manifests, application code, and the full-tree audit gate are unchanged.
• Registry integrity: all five changed records match live npm metadata, including dependency declarations, engine requirements, tarball URLs, and integrity values. Downloaded tarballs match the committed SHA-512 hashes. All 388 regular files checked across those installed packages match the registry tarballs.
• Advisory coverage: submitting all 738 package names, including development dependencies, to npm’s bulk advisory endpoint returned the specified js-yaml/SVGO advisories for the base and an empty result for HEAD. These versions also match the published fixes: YAML, SVG links, foreignObject HTML.
• YAML behavior: both baseline releases accept the repeated-empty-merge payload; both patched releases reject it at the default work budget. Ordinary merges and the exact configured budget boundary pass.
• SVG behavior: namespace-prefixed anchors, tab/newline/carriage-return URL schemes, and executable foreignObject HTML payloads are removed with removeScripts. Safe HTTPS links, harmless HTML, and unrelated custom-namespace anchors remain intact.
• Actual CSS consumer: the production CSS minimizer successfully processes percent-encoded and base64 SVG URLs, including structural CSS selectors, with correct inlining and no warnings. Existing docs.css also minimizes without warnings.
• Review configuration: the YAML passes the live official JSON schema. Its exact glob reverses the documented npm-lockfile exclusion and covers both tracked npm lockfiles. Official documentation supports explicit inclusion to override default exclusions. I found no confirmed source-coverage regression from that evidence. CodeRabbit path filters

Limitations: schema validation and documentation do not prove hosted filter behavior, including ordinary-source coverage and preservation of other exclusions. I did not inspect hosted review results or run a fresh install, complete production build, Jest suite, or the npm audit CLI. The advisory comparison used the registry endpoint directly. Local probes ran on Node 26.8.1; CI specifies Node 24. SVG probes establish the tested plugin behavior, not production exploitability or comprehensive sanitization.

Before and after review, HEAD matched the requested SHA, the worktree was clean, and the complete changed-file list contained exactly the two files above. git diff --check passed.

The first CI attempt for 3f74875049e191c7c27e829b50fc78c346807ba0 failed before govulncheck could load the packages: downloading Azure armbillingbenefits@v1.0.0 from proxy.golang.org returned an HTTP/2 INTERNAL_ERROR. The subsequent import errors follow that failed download. The failed step did not report an advisory result.

The failed jobs were rerun on the same HEAD in CI run 34620530457. No code, dependency, scanner setting or gate changed. Attempt 2 is being watched, with attempt 1 logs preserved.

Security Scanning job 103337240718 failed only its govulncheck step. npm audit (frontend), gosec, Trivy filesystem and Trivy IaC steps succeeded. The aggregate CI Success job consequently failed. All other jobs succeeded.
