Miggo AIRoot Cause Analysis

The vulnerability stems from improper handling of security constraints when no login configuration exists. The commit diff shows critical changes in AuthenticatorBase.java where security constraint checks (constraints == null) were modified to include a context.getPreemptiveAuthentication() check. In the vulnerable version (7.0.11), the absence of this check allowed unauthenticated access to protected resources when constraints were not explicitly defined. The test case added in the commit (testSecurityAnnotationsNoWebXmlLoginConfig) directly validates this scenario, confirming the function's role in the vulnerability.
