  "title": "Firefox ESR: A compromised content process could send a message to the parent process that would cause the \u0027Click\u2026",
  "description": "A compromised content process could send a message to the parent process that would cause the \u0027Click to Play\u0027 permission prompt to be shown. However, due to lack of validation from the parent process, if the user accepted the permission request an attacker-controlled permission would be granted rather than the \u0027Click to Play\u0027 permission. This vulnerability affects Firefox \u003C 70.",
