Уязвимость утечки IP-адреса пользователя через использование View Source в браузерах Mozilla Firefox и Thunderbird
Описание
Когда расширение с разрешением прокси зарегистрировано для получения <all_urls>, обратный вызов proxy.onRequest не срабатывает для URL-адресов с префиксом view-source. Хотя веб-контент не может перейти по таким URL, пользователь, открывая исходный код страницы (View Source), способен непреднамеренно раскрыть свой IP-адрес.
Затронутые версии ПО
- Firefox до релиза 84
- Thunderbird до релиза 78.6
- Firefox ESR до релиза 78.6

When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
