Security readout for executives and security teams
This Jenkins plugin flaw let any user with basic Overall/Read access see pending requests they should not necessarily see. The known impact is information disclosure, not code execution or system takeover. Business urgency depends on whether pending requests contain sensitive operational, access, or change-management details. Exposure is limited to Jenkins instances using the Jenkins requests-plugin Plugin version 2.2.6 or earlier, where users have Overall/Read access. Publicly exposed Jenkins increases concern, but the described prerequisite is authenticated access. Treat as a low-to-moderate operational privacy issue unless pending requests contain sensitive approvals, access requests, or change details. Prioritize during routine Jenkins hardening and plugin maintenance, with faster action for internet-facing or broadly accessible Jenkins environments. Mitigation focus: Identify Jenkins instances with requests-plugin installed.; Check whether the installed plugin version is 2.2.6 or earlier.; Review Jenkins advisory SECURITY-1995 for vendor update guidance..
