      <title>CVE-2026-41179 — RClone: Unauthenticated operations/fsinfo allows attacker-controlled backend instantiation and local command execution</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-41179</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; rclone, Red Hat OpenShift API for Data Protection, Red Hat Advanced Cluster Management for Kubernetes 2&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
