What is CVE-2026-71312?
CVE-2026-71312 is a high-severity command injection vulnerability in rclone, published on 5 Aug 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
rclone is a command-line program to sync files and directories to and from different cloud storage providers. 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.
Weakness: CWE-78
