Summary

pulp-rpm publishes a distribution tree and uses addon and variant ids from .treeinfo as directory names without restricting them to the task work area, a path traversal flaw (CWE-22). A user who can sync or upload a distribution tree with low privileges can make the publish task create a directory outside that area and write repository metadata and packages there as the Pulp worker user. Existing files and directories are not replaced, and the flaw does not disclose data or stop the service.
