Miggo AIRoot Cause Analysis

The vulnerability centers on improper security context restoration after cross-domain EJB calls. Wildfly's security architecture uses SecurityContextInterceptor to manage context switching. The missing context restoration in the 'aroundInvoke' method (specifically in the finally block that should reset the SecurityContextAssociation) directly matches the described vulnerability pattern. This is the core function responsible for pushing/popping security contexts during EJB method invocations.
