Descriptions

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.

Algunos sitios web presentan una funcionalidad "Show Password" donde al hacer clic en un botón se cambiará un campo de contraseña en un campo textbook, divulgando la contraseña escrita. Si, al usar un teclado de software que recuerda la entrada del usuario, un usuario escribió su contraseña y usó esa funcionalidad, se cambió el tipo de campo de contraseña, resultando en un cambio de distribución del teclado y la posibilidad de que el teclado de software recuerde la contraseña escrita. Esta vulnerabilidad afecta a Firefox versiones anteriores a 83, Firefox ESR versiones anteriores a 78,5 y Thunderbird versiones anteriores a 78,5
