CVE-2023-27902

First published: Wed Mar 08 2023(Updated: )

A flaw was found in Jenkins. Jenkins uses temporary directories adjacent to workspace directories, usually with the @tmp name suffix, to store temporary files related to the build. In pipelines, these temporary directories are adjacent to the current working directory when operating in a subdirectory of the automatically allocated workspace. Jenkins-controlled processes, like SCMs, may store credentials in these directories. Affected versions of Jenkins show these temporary directories when viewing job workspaces, which allows attackers with Item/Workspace permission to access their contents.
