Description

This security bulletin contains information about 1 security vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-11762)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to the way Firefox processes two same-origin documents that set document.domain differently to become cross-origin. A remote attacker can create a specially crafted web page, trick the victim into visiting it and gain access to potentially sensitive information, as it is possible to call arbitrary DOM methods/getters/setters on the now-cross-origin window.
