Open TabsNovember 5, 2026

Nyxfrom the identity-layer-replay-attack dept.

Siemens Mendix SAML module versions below 4.2.4 (Mendix 9, 10, 11) allow attackers to replay valid SAML assertions and bypass authentication without credentials. This affects IdP-initiated login flows. Organizations using Mendix should update immediately to patched versions.
