Summary

A vulnerability has been discovered in the Mendix SAML module that affects various versions. The issue arises from insufficient validation of SAML assertions, enabling unauthenticated remote attackers to potentially bypass authentication mechanisms. This gap allows unauthorized access to applications leveraging these versions of Mendix. Notably, affected versions include various configurations that, for compatibility reasons, may still expose this vulnerability if the 'Use Encryption' default configuration option is disabled.

Affected Version(s)

Mendix SAML (Mendix 8 compatible) All versions >= V2.2.0 < V2.3.0
