What is GHSA-6rmx-gvvg-vh6j?
GHSA-6rmx-gvvg-vh6j is a denial of service vulnerability in openclaw, published on 9 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
