Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 98

Thunderbird versions prior to 91.7
Description
The issue is related to a logical error in handling iframes. If an attacker could control the contents of an iframe sandboxed with
allow-popups but not allow-scripts, they were able to craft a link that, when clicked, would lead to JavaScript execution in violation of the sandbox. This could allow a remote attacker to bypass introduced security restrictions.Recommendations
For Firefox versions prior to 98, update to version 98 or later.
For Firefox ESR versions prior to 91.7, update to version 91.7 or later.
For Thunderbird versions prior to 91.7, update to version 91.7 or later.
