Operationally, ranked in the top 6.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Jenkins TestComplete support Plugin 2.8.1 and earlier contains a stored cross-site scripting vulnerability because it fails to escape the TestComplete project name when rendering configuration or build views. The affected component is the Jenkins plugin that integrates TestComplete test projects into Jenkins jobs, and the flaw is tracked as CWE-79 with a CVSS 3.1 score of 5.4.
Attackers who possess Item/Configure permission on a Jenkins item can supply a malicious project name that is stored and later executed in the browsers of other users who view the affected job configuration or results, enabling theft of session tokens or other actions within the Jenkins web interface.
The Jenkins security advisory published on 2023-05-16 at the referenced URL describes the issue under SECURITY-2892 and directs administrators to update the plugin to a version that properly escapes the project name.
The EPSS score reached a peak of 0.1345 with a current value of 0.1172, indicating moderate but not sharply rising exploitation interest after disclosure.
