Miggo AIRoot Cause Analysis

The vulnerability stems from two key points: 1) Lack of input sanitization when storing event descriptions (CWE-79), and 2) Unsafe output encoding when rendering stored content. The advisory specifically mentions malicious links in <a> tags, indicating both storage and display phases are vulnerable. While exact filenames aren't provided, Apache OpenMeetings' architecture patterns suggest these would be found in event management controllers and corresponding JSP views.
