Deeper analysis
CVE-2022-34173 is a cross-site scripting vulnerability in Jenkins versions 2.340 through 2.355 inclusive. It stems from the build button tooltip in list views rendering HTML without escaping the job display name, allowing untrusted content to execute in the context of other users.
Attackers with Job/Configure permission can supply a malicious job display name that triggers script execution when another user views the affected list. Successful exploitation yields limited impact on confidentiality and integrity with no availability effect, consistent with the reported CVSS 5.4 score.
The Jenkins security advisory published on 2022-06-22 details the issue under SECURITY-2781 and directs administrators to upgrade to a fixed release that properly escapes the display name in the tooltip.
EPSS for the CVE rose from a low baseline to a peak of 0.1182 on 2025-12-11 before receding to the current value of 0.0272, indicating that exploitation interest increased well after initial disclosure.
