GHSA-7fpj-9hr8-28vh
LOWGHSA-7fpj-9hr8-28vh is a low-severity (CVSS 3.4) CWE-273 vulnerability in org.keycloak:keycloak-services. O3 Security confirms whether GHSA-7fpj-9hr8-28vh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Keycloak vulnerable to impersonation via logout token exchange
Blast Radius
org.keycloak:keycloak-services☕org.keycloak:keycloak-servicesReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Keycloak was found to not properly enforce token types when validating signatures locally. An authenticated attacker could use this flaw to exchange a logout token for an access token and possibly gain access to data outside of enforced permissions.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.keycloak:keycloak-services | all versions | 22.0.10 |
| ☕Maven | org.keycloak:keycloak-services | ≥ 23.0.0&&< 24.0.3 | 24.0.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.keycloak:keycloak-services. 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 org.keycloak:keycloak-services to 22.0.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7fpj-9hr8-28vh 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-7fpj-9hr8-28vh 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-7fpj-9hr8-28vh. 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-7fpj-9hr8-28vh in your dependencies?
O3 detects GHSA-7fpj-9hr8-28vh across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
