Name of the Vulnerable Software and Affected Versions Thunderbird versions prior to 52.3 Firefox ESR versions prior to 52.3 Firefox versions prior to 55

Description The issue is related to the bypassing of same-origin policy protections on pages with embedded iframes during page reloads. This allows iframes to access content on the top-level page, leading to information disclosure. The vulnerability can be exploited by a remote attacker to gain unauthorized access to protected information using iframes during page reload.

Recommendations For Thunderbird versions prior to 52.3, update to version 52.3 or later. For Firefox ESR versions prior to 52.3, update to version 52.3 or later. For Firefox versions prior to 55, update to version 55 or later.
