Background
The Jenkins Role-based Authorization Strategy Plugin is a Maven package that provides role-based authorization for Jenkins, an open-source automation server. It allows administrators to define roles and assign permissions to users or groups. This plugin is widely used in Jenkins installations to control access and permissions within the system.
Vulnerability Detail
The Role-based Authorization Strategy Plugin versions 2.12 and newer utilize a caching mechanism to improve permission lookups. However, in versions 3.0 and earlier, this cache is not properly invalidated when an administrator modifies the permission configuration. As a result, permissions that were revoked or modified may still be granted to users or groups. This vulnerability can lead to unauthorized access and potential privilege escalation within the Jenkins system.
