An attacker could cause a select dropdown to be shown over another tab; this could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5.
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
