How severe is GHSA-p674-hh8x-rv5h?

GHSA-p674-hh8x-rv5h has a CVSS score of 9.1/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-p674-hh8x-rv5h?

GHSA-p674-hh8x-rv5h affects the following packages: org.jenkins-ci.plugins:nuget (Maven). Ecosystems affected: Maven.

How do I fix GHSA-p674-hh8x-rv5h?

Update org.jenkins-ci.plugins:nuget to 1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p674-hh8x-rv5h is resolved across your whole dependency graph.

How do I detect GHSA-p674-hh8x-rv5h in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:nuget. 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.

How do I mitigate GHSA-p674-hh8x-rv5h if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-p674-hh8x-rv5h?

O3 pinpoints whether GHSA-p674-hh8x-rv5h is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-p674-hh8x-rv5h actively exploited in the wild?

No public exploit code has been indexed for GHSA-p674-hh8x-rv5h 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.

What is the EPSS score for GHSA-p674-hh8x-rv5h?

GHSA-p674-hh8x-rv5h has an EPSS (Exploit Prediction Scoring System) score of 1.5%, placing it in the 72th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-p674-hh8x-rv5h published, and has it been updated?

GHSA-p674-hh8x-rv5h was published on May 24, 2022 and was last updated on February 16, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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 Nuget Plugin 1.0 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This XML parser is used for the "Build on NuGet updates" feature.

This allows attackers with the ability to control the contents of the packages.config file in a workspace to have Jenkins parse a crafted XML document that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Jenkins Nuget Plugin 1.1 disables external entity resolution for its XML parser.
