The host is installed with Jenkins LTS through 2.263.2 or Jenkins rolling release through 2.275 and is prone to an arbitrary file read vulnerability. A flaw is present in the application, which fails to properly handle an time-of-check to time-of-use (TOCTOU) race condition issue in workspace browsers. Successful exploitation allows attackers with Job/Workspace permission and the ability to control workspace contents, e.g., with Job/Configure permission or the ability to change SCM contents, to create symbolic links that allow them to access files outside workspaces using the workspace browser.
