From 1c3a83c4baddac85a07004bd61b3647f86cb93ef Mon Sep 17 00:00:00 2001 From: shankar0123 Date: Sun, 26 Apr 2026 15:10:32 +0000 Subject: [PATCH] =?UTF-8?q?fix(bundle-8):=20Frontend=20Hardening=20?= =?UTF-8?q?=E2=80=94=202=20audit=20findings=20closed=20+=203=20partial?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes Audit-2026-04-25 L-015 (Low) and L-019 (Low) — both verified-already-clean at HEAD; new CI regression guards prevent regression. Partial closures for M-009, M-010, M-026 — Bundle 8 ships the helpers + contract tests + a soft CI budget guard, defers the long-tail per-page migrations to a new tracker ID M-029. What changed - web/src/utils/safeHtml.ts (NEW) — sanitizeHtml() chokepoint for any future code that genuinely needs dangerouslySetInnerHTML. Bundle-8 placeholder body throws — DOMPurify dependency is the activation procedure documented in the file header. - web/src/components/ExternalLink.tsx (NEW) — single chokepoint for target="_blank" anchors. Hardcodes rel="noopener noreferrer". - web/src/hooks/useListParams.ts (NEW) — URL-state hook for filter / sort / pagination state on list pages. Canonicalises the existing DashboardPage useSearchParams pattern. Per-page migrations of the ~14 remaining list pages tracked as M-029. - web/src/hooks/useTrackedMutation.ts (NEW) — useMutation wrapper enforcing the M-009 invalidation contract via discriminated-union type: caller MUST declare invalidates: QueryKey[] OR invalidates: 'noop' + noopReason: string. - 4 new Vitest test files — full unit coverage for ExternalLink (target/rel preservation), safeHtml (placeholder throws + activation hint), useListParams (URL contract / defaults / filter-resets-page), useTrackedMutation (invalidate-then-onSuccess / noop variant). - .github/workflows/ci.yml — three new regression guards: Bundle-8 / L-015: greps for any target="_blank" outside ExternalLink that lacks rel="noopener noreferrer"; clean at HEAD. Bundle-8 / L-019: greps for any dangerouslySetInnerHTML outside safeHtml.ts; clean at HEAD (0 sites). Bundle-8 / M-009: SOFT budget guard — useMutation sites must not exceed invalidation sites + 5. At HEAD: 61 mutations vs 82 invalidations + 5 = 87 budget. Stricter per-site enforcement tracked as M-029. Verification at HEAD - web/src/ target=_blank sites: 3 (all in OnboardingWizard.tsx) — all three already carry rel="noopener noreferrer". L-015 closed. - web/src/ dangerouslySetInnerHTML sites: 0. L-019 closed. - useMutation sites: 61 / invalidateQueries: 82 (M-009 budget healthy) Per-finding mapping - L-015 closed (CWE-1022) — verified-already-clean + ExternalLink component + CI grep guard. - L-019 closed (CWE-79) — verified-already-clean + safeHtml chokepoint + CI grep guard. - M-009 partial — useTrackedMutation wrapper authored; soft CI budget guard. Migrating the 56 existing useMutation sites to the wrapper tracked as M-029. - M-010 partial — useListParams hook authored + tested. Per-page migration of the ~14 list pages tracked as M-029. - M-026 partial — bundle-prompt called for XSS-hardening tests on the T-1 deferred allowlist of 14 pages. Bundle 8 ships the testing pattern via the new helpers but does NOT execute the per-page migrations — tracked as M-029. NOT addressed in this bundle (deferred to M-029) - Migrating existing 56 useMutation sites to useTrackedMutation - Migrating ~14 list pages from local useState to useListParams - Adding XSS-hardening tests to the 14 T-1-deferred pages Verification - npx tsc --noEmit → clean - npx vitest run on the 4 new Bundle-8 test files → 15/15 pass - L-015 grep guard simulation → clean - L-019 grep guard simulation → clean - M-009 budget simulation → 61 ≤ 87 (clean) - go vet ./... → clean (no backend changes) - python3 yaml.safe_load(api/openapi.yaml) → clean - python3 yaml.safe_load(.github/workflows/ci.yml) → clean Backwards compatibility - All 4 new helper files are additive; no existing call sites were modified. Existing list pages keep their useState pagination until M-029 ships per-page migrations. Bundle 8 of the 2026-04-25 comprehensive audit. Per-page migration backlog tracked as new audit finding M-029. --- .github/workflows/ci.yml | 71 ++++++++++++++ web/src/components/ExternalLink.test.tsx | 32 +++++++ web/src/components/ExternalLink.tsx | 48 ++++++++++ web/src/hooks/useListParams.test.tsx | 97 +++++++++++++++++++ web/src/hooks/useListParams.ts | 110 ++++++++++++++++++++++ web/src/hooks/useTrackedMutation.test.tsx | 83 ++++++++++++++++ web/src/hooks/useTrackedMutation.ts | 90 ++++++++++++++++++ web/src/utils/safeHtml.test.ts | 28 ++++++ web/src/utils/safeHtml.ts | 54 +++++++++++ 9 files changed, 613 insertions(+) create mode 100644 web/src/components/ExternalLink.test.tsx create mode 100644 web/src/components/ExternalLink.tsx create mode 100644 web/src/hooks/useListParams.test.tsx create mode 100644 web/src/hooks/useListParams.ts create mode 100644 web/src/hooks/useTrackedMutation.test.tsx create mode 100644 web/src/hooks/useTrackedMutation.ts create mode 100644 web/src/utils/safeHtml.test.ts create mode 100644 web/src/utils/safeHtml.ts diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 5a09a48..596485e 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -825,6 +825,77 @@ jobs: ALLOWLIST_SIZE=$(echo "$ALLOW" | tr '|' '\n' | wc -l) echo "T-1 page-coverage guardrail: clean (allowlist size: $ALLOWLIST_SIZE pages deferred)." + - name: Bundle-8 / L-015 target=_blank rel=noopener regression guard + # Audit L-015 / CWE-1022 (reverse-tabnabbing): every + # MUST carry rel="noopener noreferrer" so a malicious page at the + # target URL cannot navigate the opener window via window.opener. + # At Bundle-8 close (commit b566355→) all 3 sites in the codebase + # already comply — this guard prevents regression.
