GHSA-3h52-cx59-c456
Fix: openclaw/openclaw@5e8cb22GHSA-3h52-cx59-c456 is a CWE-696 vulnerability in openclaw. O3 Security confirms whether GHSA-3h52-cx59-c456 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw: Feishu webhook reads and parses unauthenticated request bodies before signature validation
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-3h52-cx59-c456.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.

Summary
Feishu webhook reads and parses unauthenticated request bodies before signature validation
Affected Packages / Versions
- Package:
openclaw - Affected versions:
<= 2026.3.24 - First patched version:
2026.3.25 - Latest published npm version at verification time:
2026.3.24
Details
Feishu webhook handling previously parsed JSON before signature validation, which let unauthenticated callers force full JSON parsing work before rejection. Commit 5e8cb22176e9235e224be0bc530699261eb60e53 reads the raw request body, validates the signature first, and only then parses JSON.
Verified vulnerable on tag v2026.3.24 and fixed on main by commit 5e8cb22176e9235e224be0bc530699261eb60e53.

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 2026.3.28 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3h52-cx59-c456 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 GHSA-3h52-cx59-c456 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 GHSA-3h52-cx59-c456. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3h52-cx59-c456 in your dependencies?
O3 detects GHSA-3h52-cx59-c456 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
