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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L","score":7.1},"cwes":["CWE-59","CWE-281"],"references":["https://github.com/rclone/rclone/commit/17b0c03338a857bcb0a68d2d4c82ddbdec3f7893","https://github.com/rclone/rclone/commit/a7ab39d3d1958afa1446982c1dc4e4a73a887e3e","https://github.com/rclone/rclone/releases/tag/v1.75.1","https://github.com/rclone/rclone/security/advisories/GHSA-f8g7-2xjc-7mfh","https://github.com/rclone/rclone/security/advisories/GHSA-f8g7-2xjc-7mfh"],"products":["rclone:rclone"],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-88016","score":0.00187,"percentile":0.08344,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f8g7-2xjc-7mfh","url":"https://osv.dev/vulnerability/GHSA-f8g7-2xjc-7mfh","summary":"rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination","modified":"2026-09-25T05:30:06.067766085Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":["<1.75.1"],"fixed":["1.75.1"]}]},{"id":"GO-2026-6459","url":"https://osv.dev/vulnerability/GO-2026-6459","summary":"rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination in github.com/rclone/rclone","modified":"2026-09-17T17:40:59.864498839Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":["<1.75.1"],"fixed":["1.75.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
