Name of the Vulnerable Software and Affected Versions rclone versions 1.55.0 through 1.75.1

Description A signature verification bypass exists in the stable self-update mechanism. The system incorrectly trusts checksums found in unsigned bytes that appear before the PGP-clearsigned SHA256SUMS block. An attacker who controls the release distribution path can prepend an unsigned checksum line that matches a malicious archive, leading the self-update process to install an attacker-controlled executable.

Recommendations Update rclone to version 1.75.2 or later.
