Descriptions

The sanitisation step of the Safe SVG WordPress plugin before 1.9.10 can be bypassed by spoofing the content-type in the POST request to upload a file. Exploiting this vulnerability, an attacker will be able to perform the kinds of attacks that this plugin should prevent (mainly XSS, but depending on further use of uploaded SVG files potentially other XML attacks).

El paso de saneo del plugin Safe SVG de WordPress versiones anteriores a 1.9.10, puede ser omitido al suplantar el tipo de contenido en la petición POST para subir un archivo. Explotando esta vulnerabilidad, un atacante podrá llevar a cabo los tipos de ataques que este plugin debería prevenir (principalmente de tipo XSS, pero dependiendo del uso posterior de los archivos SVG subidos, potencialmente otros ataques XML)
