Published: 30 June 2022
Summary
CVE-2022-34783 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Plot. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 3.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Plot Plugin 2.1.10 and earlier contains a stored cross-site scripting vulnerability because the plugin does not escape plot descriptions. The affected component is the Jenkins Plot Plugin, which is used to render plots within Jenkins jobs.
Attackers who possess Item/Configure permission can supply malicious content in plot descriptions that is later rendered for other users, allowing them to execute scripts in the context of the Jenkins instance and potentially access sensitive data or perform actions on behalf of victims.
The Jenkins security advisory published on 2022-06-30 details the issue under SECURITY-2220 and directs administrators to update the Plot Plugin to a version that properly escapes descriptions.
The associated EPSS score rose from a low baseline to a peak of 0.5042 on 2025-12-11 before receding to the current value of 0.3169, indicating a period of increased exploitation interest after disclosure.
