From 81b0d588fba996d4f17c6b16fba85230cf8ac114 Mon Sep 17 00:00:00 2001 From: Alexander Petric Date: Wed, 16 Sep 2026 17:29:23 -0400 Subject: [PATCH] ci: weekly Dependabot triage run with Claude Adds .github/workflows/dependabot-triage.yml, scheduled every Monday at 07:00 UTC and runnable on demand (workflow_dispatch, optional alert_numbers subset). It pages through every open Dependabot alert into .dependabot-triage/alerts.{json,tsv}, writes the per-severity and per-manifest counts to the step summary, and (when there is at least one alert) runs anthropics/claude-code-action@v1 with the triage policy in .github/prompts/dependabot-triage.md. A run produces at most one draft PR per ecosystem with targeted, checked bumps (branch security/dependabot--, title "chore(security): resolve Dependabot alerts in ") and one issue "Dependabot triage " with the severity table, proposed dismissals (reason + comment text, for a human to apply), unknowns, draft PR links and "needs a human" items. A P0 produces only a "[P0]" issue with no detail. The run never dismisses an alert, never merges, never pushes to main and never edits .github/workflows/. Tokens: the alerts are read with the default GITHUB_TOKEN under the `vulnerability-alerts: read` job permission (GitHub workflow-syntax reference: it "permits an action to list Dependabot alerts for the repository"), so no PAT is needed. Claude uses CLAUDE_CODE_OAUTH_TOKEN like the other Claude workflows. actionlint 1.7.12 does not know that permission scope yet (rhysd/actionlint#713); it is the only finding.

Only push + the `security/dependabot-*` branches you created in this run. +4. **Never edit anything under `.github/workflows/`** (a GitHub App token cannot push + workflow changes, and the triage must not change its own guard rails). +5. **Never describe a P0 or P1 in exploitable terms** anywhere public: no proof of concept, + no request shape, no vulnerable call path in issue or PR text. The alert number, package + and severity are enough. +6. Never use "No bandwidth to fix this" as a dismissal reason, and never lower a severity + because a fix is hard. + +## Severities and deadlines + +Assign severity by the **real impact in this codebase**, not by Dependabot's label: + +| Severity | Deadline | Meaning | +|---|---|---| +| P0 | 3 days | production, reachable from untrusted input, RCE / auth bypass / secret disclosure | +| P1 | 7 days | production, reachable, but needs authentication or a feature flag | +| P2 | 30 days | production, not reachable, a compatible fix exists | +| P3 | as needed | not shipped, or unreachable with no compatible fix, or a no-CVE unmaintained-crate notice | + +**Reachable** means: the advisory's trigger can receive data from a request body, a job +argument, script content, an uploaded file, a webhook, or a remote peer. Configuration we +write ourselves and test fixtures do not count as untrusted input. To decide, find the +dependency's call sites (`grep`/`rg` for the crate or package, `cargo tree -i ` in +`backend/`, `npm ls ` / `npm why ` in the JS trees) and follow the data back to +its source. If reachability cannot be determined in reasonable time, write **unknown**, +leave the severity blank and list the alert under "needs a human".

Propose dismissal with + reason `Risk is tolerable`, comment naming the manifest, e.g. "integration_tests/ + requirements.txt is a CI-only venv, not shipped". +2. **Production, unreachable, compatible fix available** → **P2**. Fix it: include the + bump in this run's draft PR for that ecosystem. No dismissal. +3. **Production, unreachable, no compatible fix** → **P3**. Propose dismissal with reason + `Vulnerable code is not actually used`, comment naming the absent call path, e.g. + "we never call `X::parse_untrusted`; only `X::from_config` on our own config". +4. **Production, reachable, but requires authentication or a feature flag** → **P1**. Fix + it (bump in the draft PR when a compatible fix exists), and list it in the issue for a + Linear ticket titled `[P1] - ` (this workflow cannot create + Linear tickets; the proposed title is enough). Keep the description non-exploitable. +5. **Production, reachable from untrusted input, RCE / auth bypass / secret disclosure** → + **P0**. **Stop.** See "P0 procedure" below. Do not open PRs, do not write the normal + issue, do not put any detail in public text. +6. **Unmaintained-crate advisories with no CVE** (RUSTSEC "unmaintained"/"unsound" + notices) → **P3**, unless the crate handles untrusted input, in which case triage it + with rules 2-5 like any other advisory. + +Severity comes from impact, never from effort: a hard fix is still P1/P2 if the impact +says so; note the difficulty under "needs a human" instead. + +## Manifest → what ships + +| Manifest | Ships? | Notes | +|---|---|---| +| `backend/Cargo.lock` | **prod** | The `windmill` binary in every image. | +| `frontend/package-lock.json` | **prod, runtime-reachable packages only** | SvelteKit with `adapter-static`, `ssr = false`, no server routes: only code bundled into the browser ships.

Print the same short text as your final message and end the run. + +## Fixing: what you may do + +Open **at most one draft PR per ecosystem** (backend cargo, wasm-parser cargo, frontend +npm, cli bun, validator npm, multiplayer npm, python uv, ...) containing every safe P1/P2 +bump for that ecosystem found in this run: + +- Branch: `security/dependabot--` from the base branch. +- Title: `chore(security): resolve Dependabot alerts in ` (the manifest path, + e.g. `backend/Cargo.lock`). +- Body: a table of alert number → package → old version → new version → severity, the + exact commands you ran, the check commands with their outcome (pass/fail and the + relevant tail of any failure), the lockfile-diff verification below, and + "Resolves Dependabot alert #" lines. Never include exploit detail. +- Create with `gh pr create --draft --base --title ... --body-file ...`. + +Safety rules for every bump: + +- Targeted updates only: `cargo update -p ` (optionally `--precise `), + `npm update ` / `npm install @`, `bun update `, `uv lock + --python 3.14 --upgrade-package `, or a direct edit of the manifest's version + constraint. **Never** a blanket `cargo update`, `npm update`, `bun update` or `uv lock + --upgrade`. +- Never a major upgrade of a direct dependency unless you have verified that every API the + repository uses is unchanged (read the changelog and every call site). Otherwise leave it + as "needs a human" with the reason. +- After each bump, inspect the lockfile diff (`git diff --stat` then `git diff `) + and confirm it contains only the intended package(s) and their necessarily updated + transitive dependencies. Revert any bump whose diff contains unexpected version changes + and report it as "needs a human". +- Respect the manifest notes above (wasm `cargo-features` line, `--python 3.14` for uv, + generated `rust-client/Cargo.toml`). +- Run the checks from `docs/validation.md` for the ecosystem you touched, and put the + results in the PR body: + - `backend/`: `SQLX_OFFLINE=true cargo check` (add the feature flags listed in + `docs/validation.md` when the bumped crate is only used behind a feature gate; + never `--features all_sqlx_features`). If the `sqlx` dependency itself moved, also run + `cargo test -p windmill-common --test sqlx_begin_cancel_safe -- --ignored`. + - `backend/parsers/windmill-parser-wasm/`: `cargo check` there (with the + `cargo-features` line restored). + - `frontend/`: `npm ci`, `npm run generate-backend-client`, `npm run check`, `npm run build`. + - `cli/`: `bun install --frozen-lockfile` (or `bun install` when the lock must change), + then `bun test test/`. + - `windmill-yaml-validator/`: `npm ci` then `npm test`. + - `python-client/wmill/`: `uv run --frozen --python 3.14 pytest tests/ -q`. + - `typescript-client/`, `multiplayer/`: `npm ci` then the package's `build` script when + it has one. + A failing check means the bump does not go into the PR: revert it and list it under + "needs a human" with the failure. +- If a check cannot run in this environment (missing service, out of time or disk), say so + explicitly in the PR body instead of claiming it passed. + +Skip a bump (and say why in the issue) when the alert has no `first_patched` version, when +the only fix is a major upgrade you could not verify, or when it is a standing decision. + +## Output: the triage issue + +Unless the P0 procedure applied, finish by creating one issue with +`gh issue create --title "Dependabot triage " --body-file `, adding +`--label security` only if `gh label list --search security` shows that label exists. +The body, in this order: + +1. **Summary table**: count per severity (P0/P1/P2/P3/unknown) and per manifest, plus the + total triaged. +2. **P0/P1 list**: alert number, package, manifest, one non-exploitable line, and for each + P1 the proposed Linear ticket title `[P1] - `. +3. **Unknowns**: alerts whose reachability you could not determine, with what you checked. +4. **Draft PRs**: one link per ecosystem PR with the alerts it resolves and the check + results in one line each. +5. **Proposed dismissals, grouped by manifest**: for each alert the number, package, the + dismissal reason (`Risk is tolerable` or `Vulnerable code is not actually used`) and the + exact comment text a human should paste. Never `No bandwidth to fix this`. +6. **Standing decisions**: the list above with the alerts they cover this week. +7. **Needs a human**: everything you could not safely do (unverified major upgrades, + failing checks, reverted bumps, ambiguous manifests), each with a reason. +8. **Per-alert table**: every triaged alert with number, package, manifest, Dependabot + severity, assigned severity, reachable (yes/no/unknown), decision. + +Put the issue URL and the draft PR URLs in your final message. + +## Working method + +1. Read `alerts.tsv`, group by manifest, and classify each manifest with the shipped table. +2. For every production alert, establish reachability from the call sites, then apply the + decision rules. Keep a scratch file under `.dependabot-triage/` with your per-alert + notes (it is git-excluded). +3. If anything is P0, run the P0 procedure and stop. +4. Otherwise, per ecosystem: create the branch, apply the safe bumps one at a time, verify + the lockfile diff after each, run the checks, commit with a message like + `chore(security): bump to (Dependabot #)`, push the branch, open the + draft PR. +5. Write the issue.
