Date: 2025-09
Affected: maven/org.jenkins-ci.main:jenkins-core, maven/org.jenkins-ci.main:jenkins-core
Attack vector: auth-bypass
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2025-59474
CWE: CWE-862
CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

Jenkins 2.527 and earlier, LTS 2.516.2 and earlier does not perform a permission check in the sidepanel of a page intentionally accessible to users lacking Overall/Read permission. This allows attackers without Overall/Read permission to list agent names through its sidepanel executors widget. Jenkins 2.528, LTS 2.516.3 removes the sidepanel from the affected view.
