GHSA-59j4-wjwp-mw9m
HIGHGHSA-59j4-wjwp-mw9m is a high-severity (CVSS 8.8) vulnerability in org.apache.velocity:velocity-engine-parent. O3 Security confirms whether GHSA-59j4-wjwp-mw9m is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
org.apache.velocity:velocity-engine-parent☕org.apache.velocity:velocityReal-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
An attacker that is able to modify Velocity templates may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. This applies to applications that allow untrusted users to upload/modify velocity templates running Apache Velocity Engine versions up to 2.2.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.apache.velocity:velocity-engine-parent | all versions | 2.3 |
| ☕Maven | org.apache.velocity:velocity | all versions | No fix |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.velocity:velocity-engine-parent. 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.apache.velocity:velocity-engine-parent to 2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-59j4-wjwp-mw9m 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-59j4-wjwp-mw9m 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-59j4-wjwp-mw9m. 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-59j4-wjwp-mw9m in your dependencies?
O3 detects GHSA-59j4-wjwp-mw9m across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
