GHSA-w86j-99wg-r29f is a high-severity (CVSS 7.4) CWE-295 vulnerability in de.tracetronic.jenkins.plugins:ecutest. O3 Security confirms whether GHSA-w86j-99wg-r29f is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jenkins TraceTronic ECU-TEST Plugin Man in the middle vulnerability
Real-World Exposure
de.tracetronic.jenkins.plugins:ecutestReal-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 man in the middle vulnerability exists in Jenkins TraceTronic ECU-TEST Plugin 2.3 and earlier in ATXPublisher.java, ATXValidator.java that allows attackers to impersonate any service that Jenkins connects to.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | de.tracetronic.jenkins.plugins:ecutest | all versions | 2.4 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for de.tracetronic.jenkins.plugins:ecutest. 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 de.tracetronic.jenkins.plugins:ecutest to 2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w86j-99wg-r29f 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-w86j-99wg-r29f 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-w86j-99wg-r29f. 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-w86j-99wg-r29f in your dependencies?
O3 detects GHSA-w86j-99wg-r29f across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
