rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, rclone core does not reject parent-directory segments in source Object.Remote() values before fs/list, fs/walk, fs/sync, and fs/operations pass those values to destination backends. A flat-keyspace source object store populated with native non-rclone tooling can contain a raw .. key segment, and affected b2, swift, qingstor, oracleobjectstorage, internetarchive, smb, storj, sftp, webdav, ftp, filelu, shade, and sia destinations use path.Join(root, remote) before EncodeDot can neutralize the segment. A copy or upload can therefore escape the configured root into another bucket, share, or path reachable by the victim credential, with sftp and smb potentially reaching other filesystem or share locations under the same login authority. This issue is fixed in version 1.75.1.

Multiple security vulnerabilities were identified and addressed in the rclone software prior to version 1.74.4. These issues were fixed in the rclone-1.74.4-1.1 package for openSUSE Tumbleweed. The vulnerabilities have a medium severity rating and a CVSS score of 8.8. A patch is available to remediate these vulnerabilities.

Rclone versions prior to 1.74.4 contain an authorization bypass vulnerability in the 'serve restic --private-repos' command. This flaw allows an authenticated user to use directory traversal sequences ('..') in the URL path to access, modify, or delete other users' private repositories. The vulnerability is due to improper sanitization of the URL path when building the backend object key, while authorization checks are performed on a routed user path segment. This issue is fixed in version 1.74.4.
