potentially exploit these to cause a denial of service, bypass security
restrictions, obtain sensitive information, or execute arbitrary code.

CVE-2022-22761, CVE-2022-22764)
It was discovered that extensions of a particular type could auto-update
themselves and bypass the prompt that requests permissions. If a user
were tricked into installing a specially crafted extension, an attacker
could potentially exploit this to bypass security restrictions.
(CVE-2022-22754)
It was discovered that dragging and dropping an image into a folder could
result in it being marked as executable. If a user were tricked into
dragging and dropping a specially crafted image, an attacker could
potentially exploit this to execute arbitrary code. (CVE-2022-22756)
It was discovered that Remote Agent, used in WebDriver, did not validate
Host or Origin headers. If a user were tricked into opening a specially
crafted website with WebDriver enabled, an attacker could potentially
exploit this to connect back to the user's browser in order to control
it. (CVE-2022-22757)
