Pull request overview

This PR tightens the password reset / password change flows by ensuring only “forgot password” expiring codes are accepted (and that invitation codes are rejected), and updates/extends test coverage accordingly.

Changes:

• Enforce a forgot-password intent prefix check when rendering /reset_password and when handling /password_change.
• Update existing tests to generate/reset codes with a forgot-password intent.
• Add negative tests to ensure invitation codes (and null-intent codes) are rejected with 422.

• The intent validation only checks for the forgot-password prefix, but the code generator sets intent to the full value FORGOT_PASSWORD_INTENT_PREFIX + userId and expires by that exact intent. With the current startsWith check, a code whose intent doesn’t match the user_id in the payload would still be accepted, undermining the purpose of intent-scoping and making it easier for mismatched/forged codes to be replayed across users if they ever exist in the store.

    private ResetPasswordResponse changePasswordCodeAuthenticated(ExpiringCode expiringCode, String newPassword) {
        String intent = expiringCode.getIntent();
        if (intent == null || !intent.startsWith(FORGOT_PASSWORD_INTENT_PREFIX)) {
            throw new InvalidCodeException("invalid_code", "Sorry, your reset password link is no longer valid. Please request a new one", 422);
        }

• checkIfUserExists logs the raw expiring code when the intent isn’t a forgot-password intent. The code value is a secret token and shouldn’t be written to logs. Also, the intent check only validates the prefix; since forgot-password codes are generated with intent FORGOT_PASSWORD_INTENT_PREFIX + user_id, it’s safer to require the full intent to match the user_id in the code payload.

        String intent = code.getIntent();
        if (intent == null || !intent.startsWith(FORGOT_PASSWORD_INTENT_PREFIX)) {
            logger.debug("reset_password ExpiringCode[{}] intent is not a forgot-password intent. Aborting.", code.getCode());
            return null;
        }
