In versions 5.0.6 and below, the eCard send handler uses a raw $_POST['ecard_message'] value instead of the HTMLPurifier-sanitized $formValues['ecard_message'] when constructing the greeting card HTML. This allows an authenticated attacker to inject arbitrary HTML and JavaScript into greeting card emails sent to other members, bypassing the server-side HTMLPurifier sanitization that is properly applied to the ecard_message field during form validation. An attack can result in any member or role receiving phishing content that appears legitimate, crossing from the web application into recipients' email clients. This issue has been fixed in version 5.0.7."}, {"lang": "es", "value": "Admidio es una soluci\u00f3n de gesti\u00f3n de usuarios de c\u00f3digo abierto.

Esto permite a un atacante autenticado inyectar HTML y JavaScript arbitrarios en correos electr\u00f3nicos de tarjetas de felicitaci\u00f3n enviados a otros miembros, eludiendo el saneamiento de HTMLPurifier del lado del servidor que se aplica correctamente al campo ecard_message durante la validaci\u00f3n del formulario.
