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.","published":"2026-06-24T17:52:33.024Z","modified":"2026-08-11T23:55:33.374372108Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","fixedVersion":"1.74.3"}],"fix":null,"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-49980.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-49980"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49980.json"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-qw24-gh76-8rvv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49980"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2492478"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T23:55:33.374372108Z"}}
