CVE-2022-34195
Published: 23 June 2022
Summary
CVE-2022-34195 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Repository Connector. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 6.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a stored cross-site scripting flaw (CWE-79) affecting the Jenkins Repository Connector Plugin in versions 2.2.0 and earlier. It arises because the plugin fails to escape the name and description fields of Maven Repository Artifact parameters when those values are rendered on views that display build parameters, producing a CVSS 5.4 exposure.
Attackers who hold Item/Configure permission can supply crafted parameter values that are stored and later executed in the browsers of other users who view the parameter pages, achieving limited impacts on confidentiality and integrity within the Jenkins application.
The Jenkins security advisory for SECURITY-2784 details mitigation steps, primarily through plugin updates that enforce proper escaping of the affected fields.
The associated EPSS score rose from a low baseline to a peak of 0.3160 on 2025-12-11 before receding to the current value of 0.0999, indicating that exploitation interest emerged after disclosure.
