CVE-2026-41176
github.com/rclone/rclone: Rclone: Unauthorized access to administrative functions through unauthenticated Remote Control endpoint.
Severity by source
Trivy's own label is CRITICAL. Rated critical by NVD, GHSA, Bitnami, Julia. Rated lower by Red Hat (high), Amazon (high), Ubuntu (medium).
Description
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.
