Miggo AIRoot Cause Analysis

The vulnerability stems from missing authorization checks for archived channels during command execution. The primary suspect is the command execution handler (ExecuteCommand) which would naturally be the entry point for processing commands. The medium-confidence HasPermissionToChannel function is included because authorization flaws often involve permission-checking utilities. Both align with CWE-863 (Incorrect Authorization) by failing to enforce archived channel state constraints.
