{"id":"UBUNTU-CVE-2026-95625","details":"The Tauri updater plugin verifies update binaries using minisign signatures, but the signature covers only the raw binary bytes. The update manifest -- which contains the version number, download URL, and signature -- is fetched over TLS but is never itself signed or authenticated. Because the only anti-rollback check compares the manifest's version field against the current version, and that field is unsigned, an attacker who can serve a crafted manifest can force installation of any older signed release without possessing the developer's private key.","modified":"2026-09-24T02:02:53.459434380Z","published":"2026-09-23T09:17:00Z","upstream":["CVE-2026-95625"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-95625"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-95625"},{"type":"REPORT","url":"https://github.com/tauri-apps/plugins-workspace"},{"type":"REPORT","url":"https://github.com/tauri-apps/plugins-workspace/commit/690dcfd694"},{"type":"REPORT","url":"https://github.com/tauri-apps/plugins-workspace/releases/tag/updater-v2.12.0"},{"type":"REPORT","url":"https://github.com/tauri-apps/plugins-workspace/security/advisories/GHSA-j38x-g3m3-95fr"}],"affected":[{"package":{"name":"minisign","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/minisign?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.11-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.11-1","binary_name":"minisign"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-95625.json"}},{"package":{"name":"minisign","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/minisign?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.12-1","0.12-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.12-1build1","binary_name":"minisign"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-95625.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
