GHSA-4fjc-fwj2-7xfg
LOWGHSA-4fjc-fwj2-7xfg is a low-severity (CVSS 3.1) CWE-319 vulnerability in org.jenkins-ci.plugins:repository-connector. O3 Security confirms whether GHSA-4fjc-fwj2-7xfg is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Credentials transmitted in plain text by Repository Connector Plugin
Real-World Exposure
org.jenkins-ci.plugins:repository-connectorReal-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
Repository Connector Plugin stores credentials in its global configuration file org.jvnet.hudson.plugins.repositoryconnector.RepositoryConfiguration.xml on the Jenkins controller as part of its configuration.
While the credentials are stored encrypted on disk, they are transmitted in plain text as part of the configuration form by Repository Connector Plugin 1.2.6 and earlier. This can result in exposure of the credential through browser extensions, cross-site scripting vulnerabilities, and similar situations.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.jenkins-ci.plugins:repository-connector | all versions | 2.0.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:repository-connector. 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.jenkins-ci.plugins:repository-connector to 2.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4fjc-fwj2-7xfg 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-4fjc-fwj2-7xfg 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-4fjc-fwj2-7xfg. 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-4fjc-fwj2-7xfg in your dependencies?
O3 detects GHSA-4fjc-fwj2-7xfg across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
