## Technical details

The vulnerability is a path traversal flaw in the hapus() function of application/modules/admin/controllers/data_galeri.php. The gbr parameter is concatenated directly into an unlink() call without path canonicalization, basename filtering, or directory restriction, allowing attackers with admin credentials to traverse to any file writable by the web server. This enables arbitrary file deletion within the webroot, including critical configuration files.
