Miggo AIRoot Cause Analysis

The vulnerable functions are likely those that handle MXC URIs. The matrix-js-sdk's failure to validate() the server-name and media-id components of these URIs is the root of the vulnerability. Functions like parseMxCUri and getHttpUriForMxc are potential candidates because they are involved in processing MXC URIs.
