CVE-2026-53810
CVE-2026-53810 is a CWE-829 vulnerability in openclaw. O3 Security confirms whether CVE-2026-53810 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw < 2026.5.18 - Arbitrary Code Execution via Unscanned Marketplace Runtime Extension Metadata
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 2026.5.18 contains a code execution vulnerability where marketplace runtime extension metadata can redirect loading toward unscanned package payloads. Attackers with trusted operator access can manipulate extension metadata to load plugin code outside reviewed package entry points, bypassing security scanning.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

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 2026.5.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-53810 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-2026-53810 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-2026-53810. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
