Use when asked to map Chrome security release notes to fixing CLs, or to find which commits correspond to CVEs in a Chrome stable update. Chrome Release → Fixing CL Mapper Maps every security fix in a Chrome Releases blog post to the Gerrit CL(s) that fixed it. Input $ARGUMENTS — a https://chromereleases.googleblog.com/... URL. If empty, ask the user for one. Procedure 1. Extract CVE → bug ID pairs from the blog post The blog HTML buries bug IDs inside <a> tags, so strip tags first. Run: curl -sL \" $URL \" | python3 -c ' import sys, re, html t = re.sub(r\"<[^>]+>\", \" \", sys.stdin.read()) t = re.sub(r\"\\s+\", \" \", html.unescape(t)) seen = set() for m in re.finditer(r\"\\[\\s*(\\d{6,})\\s*\\]\\s*(Critical|High|Medium|Low)\\s*(CVE-\\d{4}-\\d+):\\s*([^.]+?)\\.\", t): if m.group(3) in seen: continue seen.add(m.group(3)) print(f\"{m.group(3)}|{m.group(1)}|{m.group(2)}|{m.group(4).strip()}\") ' > /tmp/cve_bugs.txt cat /tmp/cve_bugs.txt If this yields nothing, the page may have changed format — fall back to grep -oE 'CVE-[0-9]{4}-[0-9]+' and grep -oE 'crbug\\.com/[0-9]+' and pair them by order. 2. Find the fixing CL for each bug Search git history in the Chromium checkout and relevant sub-repos for commits whose Bug: or Fixed: footer references the bug ID, then extract the Reviewed-on: Gerrit URL. Repo selection by component keyword: ANGLE → third_party/angle Skia, Graphite → third_party/skia PDFium → third_party/pdfium Dawn → third_party/dawn V8, Turbofan, Maglev, Turboshaft → v8 everything else → . (chromium/src) Always also fall back to . if the hinted repo has no match. cd /root/src/electron/src # chromium root (parent of electron/) lookup () { local bug= \" $1 \" repos= \" $2 \" for repo in $repos . v8 third_party/skia third_party/angle third_party/pdfium third_party/dawn; do local hits hits=$(git -C \" $repo \" log --all --since= '6 months ago' -E \\ --grep= \"(Bug|Fixed):.*\\\\b ${bug} \\\\b\" --format= '%H' 2>/dev/null | sort -u) [[ -z \" $hits \" ]] && continue while read -r h; do git -C \" $repo \" log -1 --format= '%B' \" $h \" | grep '^Reviewed-on:' | sed 's/^/ /' echo \" ↳ $(git -C \" $repo \" log -1 --format='%s' \" $h \" ) \" done <<< \" $hits \" return 0 done echo \" (not found locally)\" } Drive it from /tmp/cve_bugs.txt . Prefer the non- [M1xx] -prefixed commit subject as the canonical main CL; the [M1xx] ones are branch cherry-picks. 3. Handle misses For any bug with no local hit: git -C <repo> fetch origin then re-search --remotes (fix may be newer than the checkout). Query Gerrit directly: curl -s \"https://chromium-review.googlesource.com/changes/?q=bug:${BUG}&n=10\" | tail -n +2 | python3 -m json.tool (also try skia-review , pdfium-review , dawn-review , aomedia-review ). b/ bug format (Skia, Graphite, Dawn): These repos reference bugs as b/<id> in commit messages rather than Bug: <id> footers. The Gerrit bug: query will return nothing. Use message:<id> search instead: curl -s \"https://skia-review.googlesource.com/changes/?q=message: ${BUG} &n=5\" | tail -n +2 Apply the same pattern for dawn-review.googlesource.com when the component is Dawn. Tracing main CLs from merges: When only [M1xx] merge CLs are found, query the CL detail for cherry_pick_of_change to find the original main CL number: curl -s \"https://chromium-review.googlesource.com/changes/ ${CL_NUM} ?o=CURRENT_REVISION\" | tail -n +2 | python3 -c \" import sys, json d = json.load(sys.stdin) print(d.get('cherry_pick_of_change', 'none')) \" If still nothing and the bug was reported very recently (especially by \"Google Threat Intelligence\" or marked in-the-wild), the CL is likely still access-restricted — report it as such rather than guessing. 4. Special cases Roll CLs — skip and find the upstream fix: For components whose fixes land in upstream repos (PDFium, Dawn, Skia, Graphite, libaom, libvpx, ffmpeg), the chromium-review hit will be a Roll src/third_party/... commit. Do not report the roll CL as the fix. Instead, query the component's own Gerrit instance directly for the actual fixing CL: PDFium → pdfium-review.googlesource.com (use bug: or message: query) Dawn → dawn-review.googlesource.com (use message: query — uses b/ format) Skia / Graphite → skia-review.googlesource.com (use message: query — uses b/ format) libaom → aomedia-review.googlesource.com Only if the upstream Gerrit instance returns no results should you fall back to reporting the roll CL — in that case, include the roll CL and note that the actual fix is upstream but the specific CL could not be identified. Multiple Reviewed-on: lines in one commit body: cherry-picks keep the original line plus a new one. The first Reviewed-on: is the original CL. A bug may have multiple distinct fix CLs (fix + follow-up hardening) — list all of them. 5. Output Produce a markdown table per severity level: CVE | Bug | Component | Fix CL (main) . Link bugs as https://crbug.com/<id> . Save raw output (including all branch merges) to /tmp/cve_cls.txt and mention the path.",
