CVE-2026-70441: Vulnerability in Jenkins Project Jenkins Summary Display Plugin
Jenkins Summary Display Plugin 1.15 and earlier does not escape the job name in a JavaScript context in build report pages, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Create or Item/Configure permission.
AI Analysis
Technical Summary
Jenkins Summary Display Plugin versions prior to 1.16 fail to escape the job name in JavaScript contexts on build report pages, leading to a stored XSS vulnerability. Attackers with Item/Create or Item/Configure permissions can exploit this to execute arbitrary scripts in the context of users viewing the affected pages. This vulnerability arises from improper output encoding of user-controllable input within the plugin's UI.
Potential Impact
Successful exploitation allows attackers with certain Jenkins permissions to execute arbitrary JavaScript in the context of other users viewing build reports. This can lead to session hijacking, unauthorized actions, or other malicious activities within the Jenkins environment. However, exploitation requires the attacker to have Item/Create or Item/Configure permissions, limiting the scope of impact to users with these privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Item/Create and Item/Configure permissions to trusted users only to reduce risk. Monitor Jenkins plugin updates for a patch addressing this vulnerability.
