Prior to version 2.2.0, a Server-Side Request Forgery (SSRF) vulnerability exists in the Payment receipt PDF generation module. User-supplied HTML in the payment Notes field is passed unsanitised to the Dompdf rendering library, which will fetch any remote resources referenced in the markup. The vulnerability is exploitable directly via the PDF receipt endpoint, regardless of whether automated email attachments are enabled. This issue has been patched in version 2.2.0."

Antes de la versión 2.2.0, existe una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en el módulo de generación de PDF de recibos de pago. El HTML proporcionado por el usuario en el campo Notas del pago se pasa sin sanitizar a la biblioteca de renderizado Dompdf, que recuperará cualquier recurso remoto referenciado en el marcado. La vulnerabilidad es explotable directamente a través del endpoint del recibo PDF, independientemente de si los archivos adjuntos de correo electrónico automatizados están habilitados. Este problema ha sido parcheado en la versión 2.2.0."
