Low (2.0). EPSS 0.2% chance of exploitation in the next 30 days. Fixed in github.com/rclone/rclone 1.74.4.
rclone before 1.74.4 fails to mask special permission bits when applying source-supplied mode metadata in the local backend, allowing attackers to set setuid/setgid bits on attacker-controlled files. When copying with metadata preservation from an untrusted remote, attackers can plant a setuid binary that escalates privileges to root if rclone runs as root, or to the service account user otherwise.
