Vulnerability details
The vulnerability allows a low-privileged attacker with temporary access to a victim's authenticated session to take over that account by changing its password.
The vulnerability exists due to missing current-password verification in WeGIA's password change flow when the redir parameter selects alterar_senha.php, while the operation bypasses permission checks. A low-privileged attacker can submit a new password with a valid session CSRF token and subsequently log in without knowing the victim's original password.
