CVE-2026-22903 is a critical stack-based buffer overflow vulnerability in the WAGO 0852-1322 device's modified lighttpd server. An unauthenticated remote attacker can exploit this by sending an HTTP request with an excessively long SESSIONID cookie, causing the server to crash and potentially allowing remote code execution. The vulnerability arises due to missing stack protections, making exploitation easier and more impactful. This flaw affects the availability, integrity, and confidentiality of the device and connected systems. No patches are currently available, and no known exploits are reported in the wild yet. European organizations using WAGO 0852-1322 devices, especially in industrial automation and control systems, are at high risk. Mitigation requires network-level protections, strict input validation, and monitoring for anomalous HTTP requests. Countries with significant industrial automation sectors and WAGO market presence, such as Germany, France, and the Netherlands, are most likely to be affected. Given the critical CVSS score of 9.8, immediate attention and proactive defense measures are essential to prevent exploitation.
