A vulnerability has been identified in Mendix SAML (Mendix 7 compatible) (All versions >= V1.16.4 < V1.17.3), Mendix SAML (Mendix 8 compatible) (All versions >= V2.2.0 < V2.3.0), Mendix SAML (Mendix 9 latest compatible, New Track) (All versions >= V3.1.9 < V3.3.1), Mendix SAML (Mendix 9 latest compatible, Upgrade Track) (All versions >= V3.1.8 < V3.3.0), Mendix SAML (Mendix 9.6 compatible, New Track) (All versions >= V3.1.9 < V3.2.7), Mendix SAML (Mendix 9.6 compatible, Upgrade Track) (All versions >= V3.1.8 < V3.2.6). The affected versions of the module insufficiently verify the SAML assertions. This could allow unauthenticated remote attackers to bypass authentication and get access to the application.
For compatibility reasons, fix versions still contain this issue, but only when the recommended, default configuration option Use Encryption is disabled.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
