Miggo AIRoot Cause Analysis

The analysis focused on the changes made to handle passwords in the JabberPublisherDescriptor class. The functions getPassword() and applyPassword() were identified as vulnerable because they directly handle password storage and retrieval. The patch changes these functions to use Secret for password handling, indicating that the previous handling was insecure.
