{"cve":"CVE-2026-41179","nvd":{"published":"2026-04-23T00:16:45.947","modified":"2026-07-15T02:21:14.090","status":"Modified","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78","CWE-306","CWE-94"],"references":["https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/backend/webdav/webdav.go","https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/operations/rc.go","https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/cache.go","https://github.com/rclone/rclone/commit/2a9e952b38e03a96bf40c9eb6e8e22199865ee3b","https://github.com/rclone/rclone/releases/tag/v1.73.5"],"products":["rclone:rclone"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-41179","score":0.08585,"percentile":0.95078,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-jfwf-28xr-xw6q","url":"https://osv.dev/vulnerability/GHSA-jfwf-28xr-xw6q","summary":"RClone: Unauthenticated operations/fsinfo allows attacker-controlled backend instantiation and local command execution","modified":"2026-09-10T03:50:44.588707843Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.48.0 <1.73.5"],"fixed":["1.73.5"]}]},{"id":"GO-2026-5466","url":"https://osv.dev/vulnerability/GO-2026-5466","summary":"Unauthenticated backend instantiation in github.com/rclone/rclone","modified":"2026-08-14T15:42:03.369271133Z","packages":[{"ecosystem":"Go","name":"github.com/ncw/rclone","purl":"pkg:golang/github.com/ncw/rclone","ranges":[">=1.48.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.49.0 <1.73.5"],"fixed":["1.73.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
