Deeper analysis

Jenkins Agent Server Parameter Plugin 1.0 and earlier is affected by a stored cross-site scripting vulnerability because the plugin does not escape parameter names of agent server parameters. The flaw is tracked as CVE-2022-25191 with a CVSS 3.1 score of 5.4 and is classified under CWE-79.

Attackers who possess Item/Configure permission can supply crafted parameter names that are stored and later rendered for other users, allowing execution of arbitrary script in the context of the Jenkins controller.

The Jenkins security advisory published on 2022-02-15 details the issue under SECURITY-2268 and directs administrators to update the plugin to a version that properly escapes the parameter names.

EPSS for the CVE rose from a low baseline to a peak of 0.0507 on 2025-12-11 before receding to the current value of 0.0024, indicating a period of increased exploitation interest after disclosure.
