Which packages are affected by GHSA-5786-3qjg-mr88?

GHSA-5786-3qjg-mr88 affects the following packages: org.jenkins-ci.plugins:mercurial (Maven). Ecosystems affected: Maven.

How do I fix GHSA-5786-3qjg-mr88?

Update org.jenkins-ci.plugins:mercurial to 2.16.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5786-3qjg-mr88 is resolved across your whole dependency graph.

How do I detect GHSA-5786-3qjg-mr88 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:mercurial. 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-5786-3qjg-mr88 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-5786-3qjg-mr88?

O3 pinpoints whether GHSA-5786-3qjg-mr88 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-5786-3qjg-mr88 actively exploited in the wild?

No public exploit code has been indexed for GHSA-5786-3qjg-mr88 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-5786-3qjg-mr88?

GHSA-5786-3qjg-mr88 has an EPSS (Exploit Prediction Scoring System) score of 1.3%, placing it in the 67th 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-5786-3qjg-mr88 published, and has it been updated?

GHSA-5786-3qjg-mr88 was published on May 18, 2022 and was last updated on November 8, 2023. 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

SCMs support a number of different URL schemes, including local file system paths (e.g. using file: URLs).

Historically in Jenkins, only agents checked out from SCM, and if multiple projects share the same agent, there is no expected isolation between builds besides using different workspaces unless overridden. Some Pipeline-related features check out SCMs from the Jenkins controller as well.

This allows attackers able to configure pipelines to check out some SCM repositories stored on the Jenkins controller’s file system using local paths as SCM URLs, obtaining limited information about other projects' SCM contents
