{"id":"UBUNTU-CVE-2026-41179","details":"Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint `operations/fsinfo` is exposed without `AuthRequired: true` and accepts attacker-controlled `fs` input. Because `rc.GetFs(...)` supports inline backend definitions, an unauthenticated attacker can instantiate an attacker-controlled backend on demand. For the WebDAV backend, `bearer_token_command` is executed during backend initialization, making single-request unauthenticated local command execution possible on reachable RC deployments without global HTTP authentication. Version 1.73.5 patches the issue.","modified":"2026-06-30T18:17:39.102151785Z","published":"2026-04-23T00:16:00Z","related":["USN-8299-1"],"upstream":["CVE-2026-41179"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-41179"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-41179"},{"type":"REPORT","url":"https://github.com/rclone/rclone/security/advisories/GHSA-jfwf-28xr-xw6q"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8299-1"}],"affected":[{"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-3ubuntu0.24.04.5"}]}],"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"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.60.1+dfsg-3ubuntu0.24.04.5"},{"binary_name":"rclone","binary_version":"1.60.1+dfsg-3ubuntu0.24.04.5"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41179.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.60.1+dfsg-4ubuntu2.1"}]}],"versions":["1.60.1+dfsg-4","1.60.1+dfsg-4ubuntu1","1.60.1+dfsg-4ubuntu2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.60.1+dfsg-4ubuntu2.1"},{"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-2026-41179.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-4ubuntu3.1"}]}],"versions":["1.60.1+dfsg-4ubuntu2","1.60.1+dfsg-4ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.60.1+dfsg-4ubuntu3.1"},{"binary_name":"rclone","binary_version":"1.60.1+dfsg-4ubuntu3.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41179.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"},{"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:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
