OpsTree BuildPiper before 2.7.0 contains a path traversal vulnerability that allows authenticated users with build configuration permission to read files on the build worker by supplying unvalidated dockerfile_path and build context values. Attackers can set traversal or absolute paths such as /etc/passwd via the CI configuration endpoint, then trigger a build to disclose file contents in the build log.
