NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
