Answer in brief
CVE-2026-41179 records a Critical severity (CVSS 9.8) vulnerability in RClone: Unauthenticated operations/fsinfo allows attacker-controlled backend instantiation and local command execution. The current sources do not mark it as known exploited. The current feed maps rclone/rclone (generic), github.com/ncw/rclone (go), github.com/rclone/rclone (go), github.com/rclone/rclone (go). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
