Descriptions

Roundcube before 1.4.15, 1.5.x before 1.5.5, and 1.6.x before 1.6.4 allows stored XSS via an HTML e-mail message with a crafted SVG document because of program/lib/Roundcube/rcube_washtml.php behavior. This could allow a remote attacker

to load arbitrary JavaScript code.

Roundcube anterior a 1.4.15, 1.5.x anterior a 1.5.5 y 1.6.x anterior a 1.6.4 permiten almacenar XSS a través de un mensaje de correo electrónico HTML con un documento SVG manipulado debido al comportamiento de program/lib/Roundcube/rcube_washtml.php. Esto podría permitir que un atacante remoto cargue código JavaScript arbitrario.

Roundcube Webmail contains a persistent cross-site scripting (XSS) vulnerability that allows a remote attacker to run malicious JavaScript code.
