Operationally, ranked in the top 8.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Maven Repository Server Plugin 1.10 and earlier contains a stored cross-site scripting vulnerability because the plugin fails to escape project and build display names when rendering the Build Artifacts As Maven Repository page. The flaw is tracked as CVE-2023-35144 and carries a CVSS 3.1 score of 5.4 with CWE-79 classification.
An attacker who can modify project or build display names, typically an authenticated user with corresponding Jenkins permissions, can store malicious script content that executes in the browsers of other users who later view the affected page, resulting in limited impacts to confidentiality and integrity within the Jenkins context.
The Jenkins security advisory for SECURITY-2951, referenced at jenkins.io, describes the issue and directs administrators to available plugin updates that remediate the lack of output encoding.
EPSS for the CVE has remained flat at 0.07 with no material increase after disclosure.
