CVE-2026-29613
CVE-2026-29613 is a Missing Authentication vulnerability in openclaw. O3 Security confirms whether CVE-2026-29613 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw < 2026.2.12 - Webhook Authentication Bypass via Loopback remoteAddress Trust
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
openclawnpmDescription
OpenClaw versions prior to 2026.2.12 contain a vulnerability in the BlueBubbles (optional plugin) webhook handler in which it authenticates requests based solely on loopback remoteAddress without validating forwarding headers, allowing bypass of configured webhook passwords. When the gateway operates behind a reverse proxy, unauthenticated remote attackers can inject arbitrary BlueBubbles message and reaction events by reaching the proxy endpoint.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update openclaw to 2026.2.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-29613 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether CVE-2026-29613 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-29613. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
