CVE-2022-27202
Published: 15 March 2022
Summary
CVE-2022-27202 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Extended Choice Parameter. Its CVSS base score is 5.4 (Medium).
Operationally, ranked at the 46.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Jenkins Extended Choice Parameter Plugin 346.vd87693c5a_86c and earlier contains a stored cross-site scripting vulnerability (CWE-79) because it fails to escape the value and description fields of extended choice parameters configured as radio buttons or check boxes. This affects Jenkins instances using the plugin for parameterized jobs and carries a CVSS 3.1 score of 5.4.
Attackers who possess Item/Configure permission can supply malicious payloads in these parameter fields. When another user views or interacts with the affected job configuration, the script executes in the victim's browser context, enabling limited impacts on confidentiality and integrity across the Jenkins controller.
The Jenkins security advisory for SECURITY-2232, along with the associated oss-security postings, directs administrators to the plugin update that resolves the issue.
EPSS for this CVE rose from a low baseline to a peak of 0.1425 on 2025-12-11 before receding to the current value of 0.0024, indicating a period of increased exploitation interest well after initial disclosure.
