CVE-2026-42429
Fix: openclaw/openclaw@d7c3210CVE-2026-42429 is a CWE-863 vulnerability in openclaw. O3 Security confirms whether CVE-2026-42429 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw < 2026.4.8 - Privilege Escalation via Gateway Plugin HTTP Authentication
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
openclawnpmDescription
OpenClaw before 2026.4.8 contains a privilege escalation vulnerability in the gateway plugin HTTP authentication mechanism that escalates identity-bearing operator.read requests to runtime operator.write permissions. Attackers can exploit this by sending read-scoped requests through the gateway auth route to gain unauthorized write access to runtime operations.

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 2026.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-42429 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-2026-42429 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-2026-42429. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
