{"id":"CVE-2026-104108","state":"PUBLISHED","title":"FileRise OIDC login can bind an attacker identity to an existing local account","description":"FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise maps an authenticated OIDC identity to a local account using mutable preferred_username or email claims and does not require email_verified for email-based naming. An attacker who can obtain provider-issued claims colliding with an existing local username can be logged in as that account, including the built-in administrator, even when automatic provisioning is disabled. Exploitability depends on the configured identity provider allowing the colliding claim. This issue is fixed in version 3.23.0.","publishedAt":"2026-10-14T20:39:27.691Z","updatedAt":"2026-10-20T02:11:28.127Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["error311 FileRise"],"affected":[{"vendor":"error311","product":"FileRise","versions":[{"version":"< 3.23.0","status":"affected"}]}],"references":["https://github.com/error311/FileRise/security/advisories/GHSA-c5c5-mv9m-j367","https://github.com/error311/FileRise/commit/cc1118923b522baff28dca05bdd79c27f984c68a","https://github.com/error311/FileRise/releases/tag/v3.23.0"],"weaknesses":["CWE-287","CWE-290","CWE-345"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104108.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104108","state":"PUBLISHED","datePublished":"2026-10-14T20:39:27.691Z","dateUpdated":"2026-10-20T02:11:28.127Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-01T18:05:14.173Z"},"containers":{"cna":{"title":"FileRise OIDC login can bind an attacker identity to an existing local account","descriptions":[{"lang":"en","value":"FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations.
