GHSA-5v66-m237-hwf7
Fix: payloadcms/payload@26d709dGHSA-5v66-m237-hwf7 is a CWE-613 vulnerability in payload. O3 Security confirms whether GHSA-5v66-m237-hwf7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Payload does not invalidate JWTs after log out
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.
payloadnpm@payloadcms/nextnpm@payloadcms/graphqlnpmDescription
Payload uses JSON Web Tokens (JWT) for authentication. After log out JWT is not invalidated, which allows an attacker who has stolen or intercepted token to freely reuse it until expiration date (which is by default set to 2 hours, but can be changed).
This issue has been fixed in version 3.44.0 of Payload.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for payload. 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 payload to 3.44.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5v66-m237-hwf7 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-5v66-m237-hwf7 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-5v66-m237-hwf7. 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-5v66-m237-hwf7 in your dependencies?
O3 detects GHSA-5v66-m237-hwf7 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
