Report: CVE-2026-41179 - RClone: Unauthenticated operations/fsinfo allows attacker-controlled backend ins
CVE ID :CVE-2026-41179 Published : April 23, 2026, 12:16 a.m. | 1 hour, 8 minutes ago Description :Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint `operations/fsinfo` is exposed without `AuthRequired: true` and accepts attacker-controlled `fs` input. Because `rc.GetFs(...)` supports inline backend definitions, an unauthenticated attacker can instantiate an attacker-controlled backend on demand. For the WebDAV backend, `bearer_token_command` is executed during backend initialization, making single-request unauthenticated local command execution possible on reachable RC deployments without global HTTP authentication. Version 1.73.5 patches the issue. Severity: 9.2 | CRITICAL Visit the link for more details, such as CVSS details, affected products, timeline, and more...
