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.","published":"2026-08-05T20:33:32.558Z","modified":"2026-09-11T03:30:52.250448930Z","cvss":{"score":6.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","fixedVersion":"1.75.0"}],"fix":{"url":"https://github.com/rclone/rclone/commit/1df2b70753286c1dfe8366078cbedfdf7f96472c","label":"rclone/rclone@1df2b70"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:30:52.250448930Z"}}
