What is CVE-2026-103870?

A directory traversal vulnerability exists in Pulp RPM when publishing a distribution tree. This flaw permits users with sync or upload capabilities to manipulate the publishing process, allowing the creation of directories outside the intended work area. As a result, repository metadata and packages can be written to unintended locations by the Pulp worker user. However, this flaw does not overwrite existing files or directories, nor does it compromise any data.
