GHSA-hgjr-xwj3-jfvw
HIGHJBoss RESTEasy vulnerable to Improper Input Validation
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
org.jboss.resteasy:resteasy-bomReal-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
JBoss RESTEasy before version 3.1.2 could be forced into parsing a request with YamlProvider, resulting in unmarshalling of potentially untrusted data which could allow an attacker to execute arbitrary code with RESTEasy application permissions.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.jboss.resteasy:resteasy-bom | all versions | 3.1.2.Final |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jboss.resteasy:resteasy-bom. 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.jboss.resteasy:resteasy-bom to 3.1.2.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hgjr-xwj3-jfvw 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-hgjr-xwj3-jfvw 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-hgjr-xwj3-jfvw. 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-hgjr-xwj3-jfvw in your dependencies?
O3 detects GHSA-hgjr-xwj3-jfvw across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
