{"id":"CVE-2026-41179","aliases":["BIT-rclone-2026-41179","GHSA-jfwf-28xr-xw6q"],"url":"https://o3.security/vulnerability/CVE-2026-41179","summary":"RClone: Unauthenticated operations/fsinfo allows attacker-controlled backend instantiation and local command execution","details":"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.","published":"2026-04-23T00:03:36.282Z","modified":"2026-07-24T17:29:57.952046953Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","fixedVersion":"1.73.5"}],"fix":{"url":"https://github.com/rclone/rclone/commit/2a9e952b38e03a96bf40c9eb6e8e22199865ee3b","label":"rclone/rclone@2a9e952"},"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/backend/webdav/webdav.go"},{"type":"WEB","url":"https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/operations/rc.go"},{"type":"WEB","url":"https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/cache.go"},{"type":"WEB","url":"https://github.com/rclone/rclone/releases/tag/v1.73.5"},{"type":"WEB","url":"https://rclone.org/changelog/#v1-73-5-2026-04-19"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-41179.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-41179"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41179.json"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-jfwf-28xr-xw6q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41179"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2460988"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/2a9e952b38e03a96bf40c9eb6e8e22199865ee3b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-24T17:29:57.952046953Z"}}
