GHSA-x83m-pf6f-pf9g

MEDIUM

GHSA-x83m-pf6f-pf9g is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in org.hibernate.validator:hibernate-validator. O3 Security confirms whether GHSA-x83m-pf6f-pf9g is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-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

A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    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.

  2. Fix

    Update org.hibernate.validator:hibernate-validator to 6.2.0.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x83m-pf6f-pf9g 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-x83m-pf6f-pf9g 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-x83m-pf6f-pf9g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
