Alert meAnalysisAIv1 – Sep 15, 2026
Authentication bypass in Siam Ordering (siam-server) 1.0.0 lets remote attackers log in as any user, merchant, or administrator by supplying a hardcoded master verification code that ships with the server. The flaw is rooted in a hardcoded credential (CWE-259) rather than a memory-safety or logic error, so every deployment of version 1.0.0 that exposes the verification endpoint is potentially affected, with full confidentiality, integrity, and availability impact once a session is obtained. No public exploit code has been identified and the EPSS score is low (0.24%, 16th percentile), but the issue is trivially severe if the code value is known or recoverable, and no vendor-released patch was identified in the available data.
