Descriptions

Same-origin policy protections can be bypassed on pages with embedded iframes during page reloads, allowing the iframes to access content on the top level page, leading to information disclosure. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Las protecciones de política del mismo origen se pueden omitir en páginas con iframes embebidos durante la recarga de páginas, lo que permite que los iframes accedan a contenido en la página de nivel más alto, lo que conduce a una divulgación de información. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 52.3, Firefox ESR en versiones anteriores a la 52.3 y Firefox en versiones anteriores a la 55.
