Doc Text:
A flaw was found in rclone. This path traversal vulnerability allows a remote attacker to craft special names in server and third-party listing responses. These crafted names, containing directory traversal sequences, could potentially enable writing outside the intended destination directory. However, current downstream protections in the local backend mitigate the risk of actual file escape.

Description OSIDB Bzimport 2026-09-22 19:59:36 UTC
rclone before 1.75.1 fails to confine names from server and third-party listing responses to the listed directory, allowing path traversal sequences in object names. Attackers can craft special names containing forward slashes and parent directory references to potentially write outside the destination root, though downstream protections in the local backend currently block actual file escape.
