CVE-2022-34788
Published: 30 June 2022
Summary
CVE-2022-34788 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Matrix Reloaded. 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
Jenkins Matrix Reloaded Plugin versions 1.1.3 and earlier contain a stored cross-site scripting vulnerability because the plugin fails to escape the agent name when rendering tooltips. The affected component is this Jenkins plugin, which is used to manage matrix-based build configurations and agent labeling within Jenkins instances.
Attackers who possess the Agent/Configure permission can supply a malicious agent name that is stored and later executed in the browsers of other users who view the affected tooltips, allowing the attacker to perform actions in the context of those users' Jenkins sessions.
The Jenkins security advisory published on 2022-06-30 recommends upgrading the Matrix Reloaded Plugin to a fixed release that properly escapes the agent name, and administrators are advised to apply the update promptly to eliminate the stored XSS vector.
The associated EPSS score rose from a low baseline to a peak of 0.1425 on 2025-12-11 before receding to the current value of 0.0910, indicating that exploitation interest increased after disclosure.
