{"id":"CVE-2026-55183","published":"2026-10-13T17:17:41.893","lastModified":"2026-10-16T20:04:29.760","description":"RClone Manager is a cross-platform GUI application designed to help users manage Rclone remotes efficiently. Prior to 0.2.7, RClone Manager starts the local rclone rcd service on 127.0.0.1:51900 with --rc-no-auth, --rc-allow-origin *, and --rc-serve. A malicious web page opened by a user while the daemon is running can therefore send cross-origin requests to the unauthenticated local API with the user's operating-system privileges. The requests can disclose configured storage credentials and potentially access, upload, modify, or exfiltrate locally stored files accessible to the user and files available through configured remotes; the advisory's possible command-execution impact remains unconfirmed. This issue is fixed in version 0.2.7.","cvssScore":9.6,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","cwes":["CWE-306"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Zarestia-Dev/rclone-manager/commit/daa379498fc1aac453bcf1864d7ea072b80ffbe8","tags":[]},{"url":"https://github.com/Zarestia-Dev/rclone-manager/releases/tag/v0.2.7","tags":[]},{"url":"https://github.com/Zarestia-Dev/rclone-manager/security/advisories/GHSA-f3qj-7hx5-q4c8","tags":[]},{"url":"https://github.com/Zarestia-Dev/rclone-manager/security/advisories/GHSA-f3qj-7hx5-q4c8","tags":[]}],"exploitRefs":[{"url":"https://github.com/Zarestia-Dev/rclone-manager/commit/daa379498fc1aac453bcf1864d7ea072b80ffbe8","tags":[]},{"url":"https://github.com/Zarestia-Dev/rclone-manager/releases/tag/v0.2.7","tags":[]},{"url":"https://github.com/Zarestia-Dev/rclone-manager/security/advisories/GHSA-f3qj-7hx5-q4c8","tags":[]},{"url":"https://github.com/Zarestia-Dev/rclone-manager/security/advisories/GHSA-f3qj-7hx5-q4c8","tags":[]}],"hasPoc":true,"ai":{"summary":"RClone Manager had a critical authentication bypass vulnerability where the local rclone daemon was exposed on 127.0.0.1:51900 without proper authentication, allowing malicious web pages to access the API with user privileges and potentially exfiltrate credentials or files.","exploitability":"Easy to exploit with a simple cross-origin request from a malicious webpage when the daemon is running, requiring no user interaction beyond opening the page.","blast_radius":"High impact as attackers can access all locally stored files and configured remotes with the user's full privileges, potentially leading to credential theft and data exfiltration across multiple storage systems.","remediation":"Upgrade to version 0.2.7 or later which fixes the authentication bypass in the local rclone daemon service.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","rce","credential-exfiltration"],"model":"garnet-coder","analyzedAt":"2026-10-15T08:53:39.842Z"}}
