Exploited in the last 30 days

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise /api/folder/renameFolder.php authorizes an authenticated, non-folder-scoped, non-administrator with a valid CSRF token against the source folder but does not independently authorize a changed destination parent. A qualifying user who owns a source folder can move that tree beneath another user's existing folder or into the root namespace, and the operation rekeys the moved ownership and ACL records to the new path. The destination must be unused and existing victim files cannot be overwritten. Distinct pre-fix errors reveal whether a specifically guessed destination path exists, but disclose no directory listing or file contents. This issue is fixed in version 3.23.0.
