How severe is GHSA-hvmc-7g2x-r3p9?

GHSA-hvmc-7g2x-r3p9 has a CVSS score of 8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-hvmc-7g2x-r3p9?

GHSA-hvmc-7g2x-r3p9 affects the following packages: org.jenkins-ci.main:jenkins-core (Maven), org.jenkins-ci.main:jenkins-core (Maven). Ecosystems affected: Maven.

How do I fix GHSA-hvmc-7g2x-r3p9?

Update org.jenkins-ci.main:jenkins-core to 2.235.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hvmc-7g2x-r3p9 is resolved across your whole dependency graph.

How do I detect GHSA-hvmc-7g2x-r3p9 in my Maven dependencies?

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

How do I mitigate GHSA-hvmc-7g2x-r3p9 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-hvmc-7g2x-r3p9 actively exploited in the wild?

Yes. There are 2 known exploit references for GHSA-hvmc-7g2x-r3p9, including 1 documented proof-of-concept exploit on Exploit-DB and 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-hvmc-7g2x-r3p9?

GHSA-hvmc-7g2x-r3p9 has an EPSS (Exploit Prediction Scoring System) score of 6.8%, placing it in the 94th 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-hvmc-7g2x-r3p9?

GHSA-hvmc-7g2x-r3p9 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-hvmc-7g2x-r3p9 published, and has it been updated?

GHSA-hvmc-7g2x-r3p9 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.

Description

Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the tooltip content of help icons. Tooltip values can be contributed by plugins, some of which use user-specified values. This results in a stored cross-site scripting (XSS) vulnerability. Jenkins 2.252, LTS 2.235.4 escapes the tooltip content of help icons.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
