Which packages are affected by GHSA-2g4q-9vm9-9fw4?

GHSA-2g4q-9vm9-9fw4 affects the following packages: org.jenkins-ci.plugins:script-security (Maven). Ecosystems affected: Maven.

How do I fix GHSA-2g4q-9vm9-9fw4?

Update org.jenkins-ci.plugins:script-security to 1336.vf33a or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2g4q-9vm9-9fw4 is resolved across your whole dependency graph.

How do I detect GHSA-2g4q-9vm9-9fw4 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:script-security. 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-2g4q-9vm9-9fw4 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-2g4q-9vm9-9fw4?

O3 pinpoints whether GHSA-2g4q-9vm9-9fw4 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-2g4q-9vm9-9fw4 actively exploited in the wild?

No public exploit code has been indexed for GHSA-2g4q-9vm9-9fw4 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-2g4q-9vm9-9fw4?

GHSA-2g4q-9vm9-9fw4 has an EPSS (Exploit Prediction Scoring System) score of 1.0%, placing it in the 58th 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.

What type of vulnerability is GHSA-2g4q-9vm9-9fw4?

GHSA-2g4q-9vm9-9fw4 is classified as CWE-290 (CWE-290). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-2g4q-9vm9-9fw4 published, and has it been updated?

GHSA-2g4q-9vm9-9fw4 was published on May 2, 2024 and was last updated on February 4, 2026. 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 Script Security Plugin provides a sandbox feature that allows low privileged users to define scripts, including Pipelines, that are generally safe to execute. Calls to code defined inside a sandboxed script are intercepted, and various allowlists are checked to determine whether the call is to be allowed.

Multiple sandbox bypass vulnerabilities exist in Script Security Plugin 1335.vf07d9ce377a_e and earlier:

Crafted constructor bodies that invoke other constructors can be used to construct any subclassable type via implicit casts.
Sandbox-defined Groovy classes that shadow specific non-sandbox-defined classes can be used to construct any subclassable type.

These vulnerabilities allow attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
