Details

InfoPath 2010 forms’ business logic can only call into Global Assembly Cache (GAC) assemblies listed in the APTCA Assembly Allowable List. If this configuration is changed, forms can call into any assembly in the GAC where the Allow Partially Trust Callers Attribute (APTCA) is set. This configuration could allow malicious developers to access assemblies in the GAC not intended to be used by InfoPath forms.

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft InfoPath 2010 (Machine) -> Security ‘InfoPath APTCA Assembly Allowable List Enforcement’ to ‘Enabled’.
