Prior to v1.75.0, rclone interpolates remote SFTP paths into PowerShell hash commands in backend/sftp/sftp.go, and quoteOrEscapeShellPath escapes only ASCII apostrophe even though PowerShell treats U+2018, U+2019, U+201A, and U+201B as single-quote delimiters, allowing an attacker-controlled filename to terminate the intended path literal and append PowerShell statements that execute as the victim SSH account when server-side hashing is invoked. This issue is fixed in v1.75.0.","published":"2026-08-05T20:37:49.029Z","modified":"2026-09-11T03:30:48.634288829Z","cvss":{"score":8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"},"epss":{"score":0.00276,"percentile":0.20121,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","fixedVersion":"1.75.0"}],"fix":{"url":"https://github.com/rclone/rclone/commit/e122fba1a57641b63a580aa26c026903a84e2e88","label":"rclone/rclone@e122fba"},"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-2026-71312.json"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-2m8m-jhrm-w6j2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71312"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/e122fba1a57641b63a580aa26c026903a84e2e88"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:30:48.634288829Z"}}
