Description

OpenClaw's hooks HTTP handler counted hook authentication failures before rejecting unsupported HTTP methods. An unauthenticated client could send repeated non-POST requests (for example GET) with an invalid token to consume the hook auth failure budget and trigger the temporary lockout window for that client key.

The fix moves the hook method gate ahead of auth-failure accounting so unsupported methods return 405 Method Not Allowed without incrementing the hook auth limiter.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.3.2
  • Patched version: 2026.3.7
  • Latest published npm version at patch time: 2026.3.2

Impact

An unauthenticated network client that could reach /hooks/* could temporarily lock out legitimate webhook delivery when requests collapsed to the same hook auth client key, such as shared proxy or NAT topologies. Impact is limited to temporary availability loss for hook-triggered wake or automation delivery.

Verification

  • pnpm check passed
  • pnpm test:fast passed
  • focused hook regression tests passed
  • pnpm exec vitest run --config vitest.gateway.config.ts still has unrelated current-main failures in src/gateway/server-channels.test.ts and src/gateway/server-methods/agents-mutate.test.ts

Release Process Note

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.3.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6rmx-gvvg-vh6j is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Frequently Asked Questions

OpenClaw's hooks HTTP handler counted hook authentication failures before rejecting unsupported HTTP methods. An unauthenticated client could send repeated non-`POST` requests (for example `GET`) with an invalid token to consume the hook auth failure budget and trigger the temporary lockout window for that client key. The fix moves the hook method gate ahead of auth-failure accounting so unsupported methods return `405 Method Not Allowed` without incrementing the hook auth limiter. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.3.2` - Patched versi
