GHSA-5545-r4hg-rj4m is a low-severity (CVSS 2.7) CWE-73 vulnerability in org.keycloak:keycloak-quarkus-server. O3 Security confirms whether GHSA-5545-r4hg-rj4m is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Keycloak Path Traversal Vulnerability Due to External Control of File Name or Path
Real-World Exposure

Description
A vulnerability was found in Keycloak. A user with high privileges could read sensitive information from a Vault file that is not within the expected context. This attacker must have previous high access to the Keycloak server in order to perform resource creation, for example, an LDAP provider configuration and set up a Vault read file, which will only inform whether that file exists or not.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.keycloak:keycloak-quarkus-server | all versions | 26.0.6 |
| ☕Maven | org.keycloak:keycloak-quarkus-server | ≥ 25.0.0&&< 26.0.6 | 26.0.6 |
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-quarkus-server. 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-quarkus-server to 26.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5545-r4hg-rj4m 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-5545-r4hg-rj4m 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-5545-r4hg-rj4m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
