{"id":"UBUNTU-CVE-2026-49980","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.","modified":"2026-09-18T18:30:02.060951087Z","published":"2026-06-24T19:17:00Z","related":["USN-8782-1"],"upstream":["CVE-2026-49980"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-49980"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-49980"},{"type":"REPORT","url":"https://github.com/rclone/rclone/security/advisories/GHSA-qw24-gh76-8rvv"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8782-1"}],"affected":[{"package":{"name":"rclone","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.36-3","1.36-3ubuntu0.1","1.36-3ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-ncw-rclone-dev","binary_version":"1.36-3ubuntu0.2"},{"binary_name":"rclone","binary_version":"1.36-3ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49980.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.47.0+ex1-6","1.47.0+ex1-7","1.49.5-2","1.49.5-3","1.50.2-2","1.50.2-2ubuntu0.1","1.50.2-2ubuntu0.2","1.50.2-2ubuntu0.2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.50.2-2ubuntu0.2+esm1"},{"binary_name":"rclone","binary_version":"1.50.2-2ubuntu0.2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49980.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.53.3-4ubuntu1.22.04.5"}]}],"versions":["1.53.3-1","1.53.3-2","1.53.3-4","1.53.3-4ubuntu1","1.53.3-4ubuntu1.22.04.1","1.53.3-4ubuntu1.22.04.2","1.53.3-4ubuntu1.22.04.3","1.53.3-4ubuntu1.22.04.4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.53.3-4ubuntu1.22.04.5"},{"binary_version":"1.53.3-4ubuntu1.22.04.5","binary_name":"rclone"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49980.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.60.1+dfsg-3ubuntu0.24.04.6"}]}],"versions":["1.60.1+dfsg-2build1","1.60.1+dfsg-3","1.60.1+dfsg-3ubuntu0.24.04.1","1.60.1+dfsg-3ubuntu0.24.04.2","1.60.1+dfsg-3ubuntu0.24.04.3","1.60.1+dfsg-3ubuntu0.24.04.4","1.60.1+dfsg-3ubuntu0.24.04.5"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.60.1+dfsg-3ubuntu0.24.04.6"},{"binary_name":"rclone","binary_version":"1.60.1+dfsg-3ubuntu0.24.04.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49980.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60.1+dfsg-4","1.60.1+dfsg-4ubuntu1","1.60.1+dfsg-4ubuntu2","1.60.1+dfsg-4ubuntu2.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.60.1+dfsg-4ubuntu2.1","binary_name":"golang-github-rclone-rclone-dev"},{"binary_name":"rclone","binary_version":"1.60.1+dfsg-4ubuntu2.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49980.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.60.1+dfsg-4ubuntu3.2"}]}],"versions":["1.60.1+dfsg-4ubuntu2","1.60.1+dfsg-4ubuntu3","1.60.1+dfsg-4ubuntu3.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"1.60.1+dfsg-4ubuntu3.2","binary_name":"golang-github-rclone-rclone-dev"},{"binary_name":"rclone","binary_version":"1.60.1+dfsg-4ubuntu3.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49980.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
