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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"rclone","product":"rclone","versions":[{"version":"< 1.75.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":1.3,"impactScore":5.3}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-15T14:43:38.560950Z","id":"CVE-2026-88016","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-59"},{"lang":"en","value":"CWE-281"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:rclone:rclone:*:*:*:*:*:*:*:*","versionEndExcluding":"1.75.1","matchCriteriaId":"FA20072C-EAD0-4F08-B600-F0B5ECDE19D7"}]}]}],"references":[{"url":"https://github.com/rclone/rclone/commit/17b0c03338a857bcb0a68d2d4c82ddbdec3f7893","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/rclone/rclone/commit/a7ab39d3d1958afa1446982c1dc4e4a73a887e3e","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/rclone/rclone/releases/tag/v1.75.1","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/rclone/rclone/security/advisories/GHSA-f8g7-2xjc-7mfh","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/rclone/rclone/security/advisories/GHSA-f8g7-2xjc-7mfh","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Vendor Advisory"]}]}
