Published: 30 June 2022
Summary
CVE-2022-34791 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Validating Email Parameter. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 7.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability CVE-2022-34791 affects the Jenkins Validating Email Parameter Plugin in versions 1.10 and earlier. It is a stored cross-site scripting flaw (CWE-79) arising because the plugin does not escape the name and description fields of its parameter type, allowing untrusted content to be persisted and later rendered in Jenkins user interfaces.
Attackers who possess Item/Configure permission can exploit the issue by supplying crafted values for these fields. When other users subsequently view or interact with the affected job or item configuration, the injected scripts execute in their browsers, resulting in limited impacts to confidentiality and integrity as indicated by the CVSS 5.4 rating.
The Jenkins security advisory published on 2022-06-30 directs administrators to update the plugin to a corrected release that properly escapes the parameter metadata. The associated EPSS score rose from a low baseline to a peak of 0.1425 on 2025-12-11 before receding to its current value of 0.0910, indicating increased exploitation interest after disclosure.
