Blind Cross-Site Scripting (XSS) in Teampass, versions prior to 3.1.5.16, within the password manager login functionality in the 'contraseña' parameter of the login form 'redacted/index.php'. During failed authentication attempts, the application does not properly clean or encode the information entered by the user in the username field. As a result, arbitrary JavaScript code is automatically executed in the administrator's browser when viewing failed login entries, resulting in a blind XSS condition.
