A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Rclone before 1.75.2 contains a path traversal vulnerability in serve webdav that allows unauthenticated attackers to write above the served root by sending an unvalidated '..' path component.
