CVE: CVE-2026-41176

CVSS: 9.8 (3.1) — CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Severity: CRITICAL

Status: Critical advisory

Affected

rclone rclone

Summary

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. The RC endpoint options/set is exposed without AuthRequired: true, but it can mutate global runtime configuration, including the RC option block itself. Starting in version 1.45.0 and prior to version 1.73.5, an unauthenticated attacker can set rc.NoAuth=true, which disables the authorization gate for many RC methods registered with AuthRequired: true on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods. Version 1.73.5 patches the issue.
