GHSA-rmrm-75hp-phr2
MEDIUMGHSA-rmrm-75hp-phr2 is a medium-severity (CVSS 5.3) Improper Input Validation vulnerability in org.hibernate.validator:hibernate-validator. O3 Security confirms whether GHSA-rmrm-75hp-phr2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.hibernate.validator: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.validator:hibernate-validator to 6.1.5.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rmrm-75hp-phr2 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-rmrm-75hp-phr2 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-rmrm-75hp-phr2. 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-rmrm-75hp-phr2 in your dependencies?
O3 detects GHSA-rmrm-75hp-phr2 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
