How do I fix GHSA-wcrg-92wp-4h28?

The records we use list no patched version of org.jenkins-ci.plugins:nerrvana-plugin for GHSA-wcrg-92wp-4h28. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

How do I detect GHSA-wcrg-92wp-4h28 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:nerrvana-plugin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-wcrg-92wp-4h28 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is GHSA-wcrg-92wp-4h28 actively exploited in the wild?

No public exploit code has been indexed for GHSA-wcrg-92wp-4h28 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

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

Jenkins Nerrvana Plugin 1.02.06 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers with Overall/Read permission to have Jenkins parse a crafted HTTP request with XML data that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Additionally, XML parsing is exposed as a form validation endpoint that does not require POST requests, allowing exploitation by users without Overall/Read permission via CSRF.
