CVE-2026-22171
CVE-2026-22171 is a Path Traversal vulnerability in openclaw. O3 Security confirms whether CVE-2026-22171 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw < 2026.2.19 - Path Traversal in Feishu Media Temporary File Naming
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
openclawnpmDescription
OpenClaw versions prior to 2026.2.19 contain a path traversal vulnerability in the Feishu media download flow where untrusted media keys are interpolated directly into temporary file paths in extensions/feishu/src/media.ts. An attacker who can control Feishu media key values returned to the client can use traversal segments to escape os.tmpdir() and write arbitrary files within the OpenClaw process permissions.

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 2026.2.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-22171 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-2026-22171 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-2026-22171. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
