Descriptions

Same-origin protections for the PDF viewer can be bypassed, allowing a malicious site to intercept messages meant for the viewer. This could allow the site to retrieve PDF files restricted to viewing by an authenticated user on a third-party website. This vulnerability affects Firefox ESR < 52.8 and Firefox < 60.

Las protecciones del mismo origen para el visor de PDF pueden omitirse, lo que permite que un sitio malicioso intercepte los mensajes destinados al visor. Esto podrĂ­a permitir que el sitio recupere archivos PDF restringidos para que lo visualice un usuario autenticado en un sitio web de terceros. Esta vulnerabilidad afecta a las versiones anteriores a la 52.8 de Firefox ESR y las versiones anteriores a la 60 de Firefox.
