| Mô tả | The XSLTransformer class enables external XML entity loading, including from remote documents.
This can lead to XXE injections via the Manager's import/export toolset.
The _transformPHP() method explicitly enables external entity resolution before
loading attacker-influenced XML:
$xmlDOM->substituteEntities = true; // expands all entities incl. SYSTEM
$xmlDOM->resolveExternals = true; // fetches file:// and http:// URIs
// ...
$xmlDOM->loadXML($xml); // $xml may contain attacker DOCTYPE
A Manager-level user can trigger this path through
Tools → Import/Export → Native XML Plugin.
