Mozilla security researcher moz_bug_r_a4 reported that it is possible to create a document whose URI does not match the document’s principal using XMLHttpRequest. This type of mismatch leads to incorrect results in principal-based security checks. An attacker could use this vulnerability to execute arbitrary JavaScript within the context of another site.
