## Technical details

The vulnerability exists in the users.lua update_password action and allows unauthenticated attackers to reset passwords for accounts flagged with must-reset-at-next-login by exploiting missing session validation. Successful exploitation clears the password_expiration flag and provides an immediately usable authenticated session on the system. The attack requires network access to the web interface but no prior authentication.
