{"id":"CVE-2026-104107","published":"2026-10-14T21:17:34.727","lastModified":"2026-10-15T16:17:33.343","description":"FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. In FileRise 3.22.0, the /api/file/saveFile.php operation accepts dot and dot-dot segments in its attacker-controlled folder input before ACL inheritance evaluates the uncanonicalized string. With an authenticated non-administrator session, a valid CSRF token, and inherited edit permission on a legitimate ancestor, the local filesystem or WebDAV adapter later resolves those segments as path navigation, permitting attacker-controlled file creation outside the authorized folder and, where backend credentials permit, outside the configured WebDAV root. Local storage also created directories before final containment validation and used a prefix comparison that accepted similarly named sibling roots. This issue is fixed in version 3.23.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/error311/FileRise/commit/cc1118923b522baff28dca05bdd79c27f984c68a","tags":[]},{"url":"https://github.com/error311/FileRise/releases/tag/v3.23.0","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-67p9-5q8f-586q","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-67p9-5q8f-586q","tags":[]}],"exploitRefs":[{"url":"https://github.com/error311/FileRise/commit/cc1118923b522baff28dca05bdd79c27f984c68a","tags":[]},{"url":"https://github.com/error311/FileRise/releases/tag/v3.23.0","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-67p9-5q8f-586q","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-67p9-5q8f-586q","tags":[]}],"hasPoc":true,"ai":null}
