Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
openclawnpmDescription
OpenClaw before 2026.3.25 contains an improper access control vulnerability in the HTTP /sessions/:sessionKey/kill route that allows any bearer-authenticated user to invoke admin-level session termination functions without proper scope validation. Attackers can exploit this by sending authenticated requests to kill arbitrary subagent sessions via the killSubagentRunAdmin function, bypassing ownership and operator scope restrictions.

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.
Remediation status
No patched version of openclaw has shipped for CVE-2026-34512 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2026-34512 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-2026-34512. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
