Capgo before 12.128.2 contains a flaw in the Enforce Password Policy feature: after a Super Admin enables the policy and successfully changes their password to a compliant one, the backend does not update the password-compliance state. As a result, the backend continues to treat the account as non-compliant and repeatedly forces password-reset prompts, permanently locking the Super Admin out of organization access (organization lockout / denial of service) despite valid authentication.
