{"id":"UBUNTU-CVE-2026-116190","details":"rclone from v1.56.0 before v1.75.2 contains an information disclosure vulnerability in the WebDAV backend that forwards operator-configured custom credential headers to different hosts on HTTP 3xx redirects. Attackers who control or influence a cross-host redirect can capture headers such as X-Auth-Token set via --webdav-headers and replay them against the original WebDAV service.","modified":"2026-10-28T17:50:38Z","published":"2026-10-25T14:16:00Z","upstream":["CVE-2026-116190"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116190"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116190"},{"type":"REPORT","url":"https://github.com/rclone/rclone/security/advisories/GHSA-3rqf-7h69-gg5v"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/rclone-1.56.0-before-1.75.2-webdav-credential-header-leak-on-redirect"}],"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_version":"1.36-3ubuntu0.2","binary_name":"golang-github-ncw-rclone-dev"},{"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-2026-116190.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_version":"1.50.2-2ubuntu0.2+esm1","binary_name":"golang-github-rclone-rclone-dev"},{"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-2026-116190.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"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","1.53.3-4ubuntu1.22.04.3+esm1","1.53.3-4ubuntu1.22.04.4","1.53.3-4ubuntu1.22.04.4+esm1","1.53.3-4ubuntu1.22.04.5","1.53.3-4ubuntu1.22.04.5+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.53.3-4ubuntu1.22.04.5+esm1"},{"binary_version":"1.53.3-4ubuntu1.22.04.5+esm1","binary_name":"rclone"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116190.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"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-3ubuntu0.24.04.4+esm1","1.60.1+dfsg-3ubuntu0.24.04.5","1.60.1+dfsg-3ubuntu0.24.04.5+esm1","1.60.1+dfsg-3ubuntu0.24.04.6","1.60.1+dfsg-3ubuntu0.24.04.6+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.60.1+dfsg-3ubuntu0.24.04.6+esm1"},{"binary_version":"1.60.1+dfsg-3ubuntu0.24.04.6+esm1","binary_name":"rclone"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116190.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60.1+dfsg-4ubuntu3","1.69.3+dfsg-3","1.69.3+dfsg-3ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.69.3+dfsg-3ubuntu1"},{"binary_name":"rclone","binary_version":"1.69.3+dfsg-3ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116190.json"}},{"package":{"name":"rclone","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/rclone?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60.1+dfsg-4ubuntu2","1.60.1+dfsg-4ubuntu3","1.60.1+dfsg-4ubuntu3.1","1.60.1+dfsg-4ubuntu3.1+esm1","1.60.1+dfsg-4ubuntu3.2","1.60.1+dfsg-4ubuntu3.2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rclone-rclone-dev","binary_version":"1.60.1+dfsg-4ubuntu3.2+esm1"},{"binary_name":"rclone","binary_version":"1.60.1+dfsg-4ubuntu3.2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116190.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
