CVE-2026-93986 PUBLISHED

rclone before 1.75.1 Path Traversal via Directory Listing Names

Assigner: VulnCheck
Reserved: 19.09.2026 Published: 19.09.2026 Updated: 19.09.2026

rclone before 1.75.1 fails to confine names from server and third-party listing responses to the listed directory, allowing path traversal sequences in object names. Attackers can craft special names containing forward slashes and parent directory references to potentially write outside the destination root, though downstream protections in the local backend currently block actual file escape.
