  - Content Security Policy violation report could have contained
    the destination of a redirect.

  - Multithreaded WASM triggered assertions validating separation of script
    domains.

  - noscript elements could have led to an HTML Sanitizer bypass.

  - A website's Referrer-Policy could have been be overridden, potentially
    resulting in the full URL being sent as a Referrer.

  - HTTP Auth phishing warning was omitted when a redirect is cached.

  - 'about:memory' Measure function caused an incorrect pointer operation.

  - MediaError message property could have leaked information about
    cross-origin resources.

  - Memory safety bugs.");
