CVE-2026-116191Rclone 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 '..'... Executive summary Rclone versions before 1.75.2 contain a path traversal flaw in its WebDAV server (rclone serve webdav) that lets an unauthenticated remote client create, overwrite, and move files and directories above the folder that rclone is configured to serve. The advisory rates it High with a CVSS 3.1 base score of 7.5, and it describes the impact as integrity and availability rather than data disclosure. The vendor's fix is upgrading to version 1.75.2. Technical summary The flaw is a CWE-22 path traversal caused by unvalidated '..' path elements in WebDAV requests, such as MKCOL /. which plants a directory node whose backend path is '..'. The attack needs no authentication, which the advisory says is the default for rclone serve webdav, and requires two HTTP requests (an MKCOL followed by a PUT). The advisory says it applies when the served remote has a non-empty root and the backend joins root and remote before encoding, such as webdav, ftp, sftp, http, or memory, and that local and s3 backends are not affected. Affected versions are stated as <= 1.75.1 and the patched version as 1.75.2; the advisory says the lower bound is not established. Workarounds stated: running with --read-only blocks the attack (the advisory reports MKCOL returning 405), and the advisory proposes code fixes that add path checks. Detection guidance beyond the proof-of-concept request sequence is not stated, and no CVE identifier is stated in the advisory. Summaries are generated by AI from the linked advisory text.
