From 1.46.0 until 1.74.3, rclone rcd --rc-serve accepts unauthenticated GET and HEAD requests to paths of the form: /[remote:path]/object. The remote value is parsed from the URL and passed to normal backend initialization. Inline remote configuration can set backend options that execute local commands during initialization. As a result, a single unauthenticated GET or HEAD request can execute a command as the rclone process user. This vulnerability is fixed in 1.74.3.","cvss_v4":null,"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-78"],"references":["https://github.com/rclone/rclone/security/advisories/GHSA-qw24-gh76-8rvv","https://access.redhat.com/security/cve/CVE-2026-49980","https://bugzilla.redhat.com/show_bug.cgi?id=2492478","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-49980.json"],"products":["rclone:rclone"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-49980","score":0.00781,"percentile":0.5596,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-qw24-gh76-8rvv","url":"https://osv.dev/vulnerability/GHSA-qw24-gh76-8rvv","summary":"Rclone: Unauthenticated command execution in `rclone rcd --rc-serve` via inline remote instantiation, bypassing CVE-2026-41179 fix","modified":"2026-09-10T03:50:50.290908238Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.46.0 <1.74.3"],"fixed":["1.74.3"]}]},{"id":"GO-2026-5596","url":"https://osv.dev/vulnerability/GO-2026-5596","summary":"Unauthenticated command execution in rclone rcd via inline remotes in github.com/rclone/rclone","modified":"2026-08-14T15:42:04.054189670Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.49.0 <1.74.3"],"fixed":["1.74.3"]},{"ecosystem":"Go","name":"github.com/ncw/rclone","purl":"pkg:golang/github.com/ncw/rclone","ranges":[">=1.46.0"],"fixed":[]}]}],"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).
