GHSA-xxgp-pcfc-3vgc
HIGHGHSA-xxgp-pcfc-3vgc is a high-severity (CVSS 7) CWE-592 vulnerability in org.hibernate:hibernate-validator. O3 Security confirms whether GHSA-xxgp-pcfc-3vgc is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
In Hibernate Validator 5.2.x before 5.2.5.Final, 5.3.x before 5.3.6.Final, and 5.4.x before 5.4.2.Final, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue().
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.hibernate:hibernate-validator | ≥ 5.2.0&&< 5.2.5.Final | 5.2.5.Final |
| ☕Maven | org.hibernate:hibernate-validator | ≥ 5.3.0&&< 5.3.6.Final | 5.3.6.Final |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.hibernate:hibernate-validator. 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.hibernate:hibernate-validator to 5.2.5.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xxgp-pcfc-3vgc 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-xxgp-pcfc-3vgc 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-xxgp-pcfc-3vgc. 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-xxgp-pcfc-3vgc in your dependencies?
O3 detects GHSA-xxgp-pcfc-3vgc across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
