Details

Rclone from 1.64.0 before 1.75.2 contains an authentication bypass vulnerability in serve webdav that lets unauthenticated attackers skip authentication by sending OPTIONS requests. Attackers can probe arbitrary paths and compare Allow header values to determine whether files or collections exist, enabling namespace enumeration.
