AI Analysis
Technical Summary
CVE-2026-53439 is a permission check vulnerability in Jenkins up to version 2.567 (and LTS 2.555.2) that permits attackers who have Overall/Read permission to obtain information about other users' configured timezones and to list the names of views in other users' personal "My Views". This information disclosure arises from insufficient access control enforcement in the affected Jenkins versions.
Potential Impact
The vulnerability allows an attacker with Overall/Read permission to gain limited sensitive information about other users, specifically their timezone configuration and the names of their personal views. This does not impact integrity or availability but results in a confidentiality breach of user-specific configuration data.
Mitigation Recommendations
Patch status is not yet confirmed — check the Jenkins Project vendor advisory for current remediation guidance. Until an official fix is released, review user permissions carefully to limit Overall/Read access only to trusted users to reduce exposure.
