CVE-2012-0958
content/unity-api.js in the unity-firefox-extension extension 2.4.1 for Firefox exposes the toDataURL function in an API call, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted webpage.
Does this matter?
Lower severity and a low EPSS score (1.58%). Track it; it rarely justifies an emergency change on its own.
