Summary
OpenClaw has pre-auth webhook body parsing that can enable unauthenticated slow-request DoS
Details

Impact

OpenClaw webhook handlers for BlueBubbles and Google Chat accepted and parsed request bodies before authentication and signature checks on vulnerable releases. This allowed unauthenticated clients to hold parser work open with slow/oversized request bodies and degrade availability (slow-request DoS).

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected releases: <= 2026.3.1
  • Latest published vulnerable version at triage time: 2026.3.1 (npm)
  • Fixed release: 2026.3.2 (released)

Fix Commit(s)

  • d3e8b17aa6432536806b4853edc7939d891d0f25

Mitigation

Upgrade to 2026.3.2 (or newer). The fix enforces auth-before-body for affected webhook paths, adds strict pre-auth body/time budgets, and introduces shared in-flight/request guardrails with regression coverage.
