Prior to 1.75.1, when backend/local runs with --links, a source .rclonelink object can plant a symlink in the destination and later directory metadata is applied through that path. MkdirMetadata, writeMetadataToFile, and setTimes operate when Directory.translatedLink=false, so os.Chown, os.Chmod, os.Chtimes, and birth-time handling can bypass os.Root confinement and follow the symlink. An attacker controlling source contents can therefore apply selected ownership, permissions, modification times, or birth times to a file or directory outside the destination, with --metadata required for chmod and chown while modification time is applied by the normal directory workflow. This issue is fixed in version 1.75.1.","published":"2026-09-10T16:18:08.637","modified":"2026-09-10T16:18:08.637","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/rclone/rclone/commit/17b0c03338a857bcb0a68d2d4c82ddbdec3f7893","label":"rclone/rclone@17b0c03"},"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/commit/17b0c03338a857bcb0a68d2d4c82ddbdec3f7893"},{"type":"WEB","url":"https://github.com/rclone/rclone/commit/a7ab39d3d1958afa1446982c1dc4e4a73a887e3e"},{"type":"WEB","url":"https://github.com/rclone/rclone/releases/tag/v1.75.1"},{"type":"WEB","url":"https://github.com/rclone/rclone/security/advisories/GHSA-f8g7-2xjc-7mfh"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T16:18:08.637"}}
