{"id":"CVE-2026-88016","summary":"rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination","details":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. 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.","aliases":["GHSA-f8g7-2xjc-7mfh"],"modified":"2026-09-12T03:47:21.197038903Z","published":"2026-09-10T15:53:39.550Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-281","CWE-59"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88016.json"},"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/releases/tag/v1.75.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88016.json"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-f8g7-2xjc-7mfh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88016"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/17b0c03338a857bcb0a68d2d4c82ddbdec3f7893"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/a7ab39d3d1958afa1446982c1dc4e4a73a887e3e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rclone/rclone","events":[{"introduced":"0"},{"fixed":"17b0c03338a857bcb0a68d2d4c82ddbdec3f7893"},{"fixed":"a7ab39d3d1958afa1446982c1dc4e4a73a887e3e"},{"fixed":"687d264b689b8c49a67e2e52a8a5e0caa01c04ce"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.75.1"}]}}],"versions":["v1.75.0","v1.74.0","v1.73.0","v1.72.0","v1.71.0","v1.70.0","v1.69.0","v1.68.0","v1.67.0","v1.66.0","v1.65.0","v1.64.0","v1.63.0","v1.62.0","v1.61.0","v1.60.0","v1.59.0","v1.58.0","v1.57.0","v1.56.0","v1.55.0","v1.54.0","v1.53.0","v1.52.0","v1.51.0","v1.50.0","v1.49.0","v1.48.0","v1.47.0","v1.46.0","v1.46","v1.45","v1.44","v1.43","v1.42","v1.41","v1.40","v1.39","v1.38","v1.37","v1.36","v1.35","v1.34","v1.33","v1.32","v1.31","v1.30","v1.29-1-gbb75d80","v1.29","v1.28","v1.27","v1.26","v1.25","v1.24","v1.23","v1.22","v1.21","v1.20","v1.19","v1.18","v1.17","v1.16","v1.15","v1.14","v1.13","v1.12","v1.11","v1.10","v1.09","v1.08","v1.07","v1.06","v1.05","v1.04","v1.03","v1.01","v1.00","v0.99","v0.98","v0.97","v0.96","v0.95","v0.94","v0.93","v0.92","v0.91","v0.90"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-88016.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L"}]}
