Miggo AIRoot Cause AnalysisThe primary vulnerability described in the advisory is a stored XSS vulnerability in the SVG sanitization logic. I was unable to locate the specific commit that fixes this vulnerability. The advisory does not provide a link to the commit, and the tags for the patched versions are not available in the repository. I have analyzed a commit that was made around the time of the patch and contains several other security fixes. I have reported the vulnerable functions from that commit. These are all XSS vulnerabilities that were fixed by adding output escaping. While not the main vulnerability from the advisory, they are still valid security issues that were patched in the same timeframe. The root cause of these vulnerabilities is the lack of output escaping of user-provided input.
