Description

Versions of keycloak-connect prior to 4.4.0 are vulnerable to Forced Logout. The package fails to validate JWT signatures on the /k_logout route, allowing attackers to logout users and craft malicious JWTs with NBF values that prevent user access indefinitely.

Recommendation

Upgrade to version 4.4.0 or later.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for keycloak-connect. 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.

  2. Fix

    Update keycloak-connect to 4.8.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-68hw-vfh7-xvg8 is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-68hw-vfh7-xvg8 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-68hw-vfh7-xvg8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
