{"cve":"CVE-2026-41176","nvd":{"published":"2026-04-23T00:16:45.800","modified":"2026-07-15T02:21:13.883","status":"Modified","description":"Rclone is a command-line program to sync files and directories to and from different cloud storage providers. The RC endpoint `options/set` is exposed without `AuthRequired: true`, but it can mutate global runtime configuration, including the RC option block itself. Starting in version 1.45.0 and prior to version 1.73.5, an unauthenticated attacker can set `rc.NoAuth=true`, which disables the authorization gate for many RC methods registered with `AuthRequired: true` on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods. 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-306","CWE-15"],"references":["https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/config.go","https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/rcserver/rcserver.go","https://github.com/rclone/rclone/security/advisories/GHSA-25qr-6mpr-f7qx","https://access.redhat.com/security/cve/CVE-2026-41176","https://bugzilla.redhat.com/show_bug.cgi?id=2460989"],"products":["rclone:rclone"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-41176","score":0.32715,"percentile":0.98346,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-25qr-6mpr-f7qx","url":"https://osv.dev/vulnerability/GHSA-25qr-6mpr-f7qx","summary":"Rclone: Unauthenticated options/set allows runtime auth bypass, leading to sensitive operations and command execution","modified":"2026-09-10T03:50:42.132350137Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.45.0 <1.73.5"],"fixed":["1.73.5"]}]},{"id":"GO-2026-4964","url":"https://osv.dev/vulnerability/GO-2026-4964","summary":"Rclone: Unauthenticated options/set allows runtime auth bypass, leading to sensitive operations and command execution in github.com/rclone/rclone","modified":"2026-06-30T13:59:23.001026518Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":["<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).
