  1. CVE-2026-76992 7.5 Élevée

    CODESYS Development System 3 · CODESYS Gateway · CODESYS Edge Gateway for Windows · CODESYS HMI (SL)

    The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in a denial-of-service condition thus leading to a total loss of availablity.
