CVE-2026-79781Source published Source updated
rclone serve s3 before 1.74.4 contains a path traversal vulnerability that allows attackers to read and overwrite root-level files by using dot-dot segments in S3 object keys. Attackers can send requests with object keys like../root-secret.txt to escape the bucket namespace and access files in the serve root directory. A flaw was found in rclone.
