Miggo AIRoot Cause Analysis

The vulnerability stems from line 242-243 in the original code where the check 'if special in entry:' erroneously looked for virtual group keywords in the group NAME string rather than the group MEMBERS list. The commit diff shows the fix changed this to check 'this_group' (the group members) instead of 'entry' (the group name). This function is the core ACL evaluation mechanism that determines user permissions, making it the clear source of improper access control.
