Miggo AIRoot Cause Analysis

The vulnerability stems from two key issues: 1) receiveMessage() in the iframe implementation lacks origin validation despite handling sensitive localStorage operations, as explicitly stated in CVE-2015-9544 description. 2) buildMessage() in the client code uses insecure wildcard targetOrigin when sending messages, as shown in the code snippets from GitHub issues and the pull request attempting to fix it. Both functions are directly referenced in vulnerability descriptions and code analysis from multiple sources including NVD, GitHub advisory, and the project's own issue tracker.
