{"id":"CVE-2026-49980","summary":"Rclone: Unauthenticated command execution in `rclone rcd --rc-serve` via inline remote instantiation, bypassing CVE-2026-41179 fix","details":"Rclone is a command-line program to sync files and directories to and from different cloud storage providers. 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.","aliases":["GHSA-qw24-gh76-8rvv"],"modified":"2026-06-28T04:03:51.288648939Z","published":"2026-06-24T17:52:33.024Z","related":["openSUSE-SU-2026:10975-1"],"database_specific":{"cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49980.json","cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rclone/rclone","events":[{"introduced":"eb85ecc9c480175bd39a2009212ffa81eaebee7c"},{"fixed":"37e4117f48bdef0fa1ba27f6467d7a891b0b55ba"}],"database_specific":{"extracted_events":[{"introduced":"1.46.0"},{"fixed":"1.74.3"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.74.2","v1.74.1","v1.74.0","v1.73.0","v1.72.0","v1.71.0","v1.70.0","v1.69.0","v1.68.0","v1.67.0","v1.66.0","v1.65.0","v1.64.0","v1.63.0","v1.62.0","v1.61.0","v1.60.0","v1.59.0","v1.58.0","v1.57.0","v1.56.0","v1.55.0","v1.54.0","v1.53.0","v1.52.0","v1.51.0","v1.50.0","v1.49.0","v1.48.0","v1.47.0","v1.46.0","v1.46"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-49980.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
