Doc Text:
A flaw was found in rclone, a command-line program for syncing files. The local backend's filename encoder, when configured in certain ways, can improperly decode remote filenames. This allows an attacker to craft a source object that, when processed, can create or overwrite files outside the intended destination directory.

Description OSIDB Bzimport 2026-08-05 21:11:25 UTC 
rclone is a command-line program to sync files and directories to and from different cloud storage providers. From v1.51.0 until v1.75.0, the local backend in backend/local/local.go relies on the configurable filename encoder to prevent remote filename data from becoming operating-system path syntax, so a local destination using Slash, None, Raw, or on Windows an encoding that preserves backslash can decode a standard-encoded fullwidth dot-dot component or native backslash form into an actual parent-directory component before filepath.Join resolves it outside the configured local root, allowing an attacker-controlled source object to create or overwrite files outside the selected destination directory as the rclone process. This issue is fixed in v1.75.0.
