This vulnerability in Siam Ordering (siam-server) 1.0.0 arises from the presence of a hardcoded master verification code. This flaw enables remote attackers without authentication to bypass normal login procedures and gain access as any user, merchant, or administrator. The vulnerability is publicly known but lacks a CVSS score and official remediation guidance. No exploits are currently reported in the wild.

The impact of this vulnerability is significant as it allows complete authentication bypass, granting attackers unauthorized access to any account type, including administrative accounts. This could lead to unauthorized data access, manipulation, or other malicious activities within the Siam Ordering system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected system and monitor for unauthorized access attempts. Avoid using the affected version in production environments if possible.
