CVE-2026-71312 Details
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.
A command injection vulnerability has been identified in Rclone versions prior to 1.75.0, specifically within the SFTP backend. The issue arises because Rclone's quoting mechanism for remote SFTP paths in PowerShell commands only accounts for ASCII apostrophes. PowerShell also recognizes certain Unicode smart quotes as single-quote delimiters. This oversight allows an attacker to craft a filename that disrupts the intended path quotation, enabling the injection of PowerShell commands that execute under the context of the victim's SSH account, particularly when server-side hashing is performed.
Users can upgrade to Rclone version 1.75.0 or later, where this vulnerability has been fixed.
