Descriptions

The MediaError message property should be consistent to avoid leaking information about cross-origin resources; however for a same-site cross-origin resource, the message could have leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 102.

La propiedad del mensaje MediaError debe ser coherente para evitar la filtración de información sobre recursos de origen cruzado; sin embargo, para un recurso de origen cruzado del mismo sitio, el mensaje podría haber filtrado información que permitiera ataques XS-Leaks. Esta vulnerabilidad afecta a Firefox &lt; 102.

Multiple vulnerabilities have been found in Mozilla Firefox, the worst of which could result in the arbitrary execution of code. Versions less than 91.12.0:esr are affected.
