rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination

Summary With -l/--links, rclone's local backend recreates a source .rclonelink object as a real symlink at the destination verbatim preserved by design for faithful backups. Directory-metadata application, however, does not go through the os.Root sandbox and does not use NOFOLLOW syscalls. A loca...

CVE-2026-88015 rclone local: crafted Range request against a translated symlink panics (DoS)

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, backend/local with --links or links=true exposes symlink targets as .rclonelink objects, and fs.RangeOption.Decode can pass an unchecked positive Range start through...
