No confirmed exploitation observed yet

  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description

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.

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 2026.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x4vp-4235-65hg is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
