How severe is CVE-2022-25191?

CVE-2022-25191 has a CVSS score of 8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2022-25191?

CVE-2022-25191 affects the following packages: io.jenkins.plugins:agent-server-parameter (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-25191?

Update io.jenkins.plugins:agent-server-parameter to 1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-25191 is resolved across your whole dependency graph.

How do I detect CVE-2022-25191 in my Maven dependencies?

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

How do I mitigate CVE-2022-25191 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 CVE-2022-25191 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-25191 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 CVE-2022-25191?

CVE-2022-25191 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 47th 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 CVE-2022-25191?

CVE-2022-25191 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 CVE-2022-25191 published, and has it been updated?

CVE-2022-25191 was published on February 16, 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.
