Detailsinfo

A vulnerability, which was classified as critical, was found in rclone up to 1.75.1. This affects an unknown part of the component Selfupdate. The manipulation with an unknown input leads to a signature verification vulnerability. CWE is classifying the issue as CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

rclone from 1.55.0 before 1.75.2 contains a signature verification bypass in stable selfupdate that trusts checksums from unsigned bytes preceding the PGP-clearsigned SHA256SUMS block. Attackers controlling the release distribution path can prepend an unsigned checksum line matching a malicious archive, causing selfupdate to install an attacker-controlled rclone executable.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-116189 since 10/25/2026. The exploitability is told to be easy.
