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.<\/p>\n","protected":false},"excerpt":{"rendered":"
