{"id":"CVE-2026-71311","summary":"rclone: FTP Command Arguments Permit CRLF Injection When Custom Encoding Preserves Newlines","details":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.0, a valid but nondefault FTP filename encoding in backend/ftp/ftp.go can restore raw CR/LF immediately before an attacker-controlled path is interpolated into the line-oriented FTP control channel, and github.com/jlaffaye/ftp formats the argument through textproto.Conn.Cmd without rejecting CR or LF, allowing a filename such as victim CRLF DELE other-secret CRLF NOOP to inject an independent authenticated FTP command when the victim copies or syncs to a more-privileged FTP destination. This issue is fixed in 1.75.0.","aliases":["BIT-rclone-2026-71311","GHSA-8c48-q9wj-3w37","GO-2026-6187"],"modified":"2026-09-11T03:30:52.250448930Z","published":"2026-08-05T20:33:32.558Z","related":["openSUSE-SU-2026:21761-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-93"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71311.json"},"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/releases/tag/v1.75.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71311.json"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-8c48-q9wj-3w37"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71311"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/1df2b70753286c1dfe8366078cbedfdf7f96472c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rclone/rclone","events":[{"introduced":"0"},{"fixed":"1df2b70753286c1dfe8366078cbedfdf7f96472c"},{"fixed":"9ee9d0a0cafd5e5fe3b271d2280b090ab6e64048"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.75.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["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-2026-71311.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:H"}]}
