Miggo AIRoot Cause Analysis

The commit diff shows the vulnerability was fixed by adding HTML entity encoding to the username value in renderAuthorName function. This indicates the function previously lacked proper output encoding for user-controlled input (username), making it susceptible to XSS. The CWE-79 classification and advisory descriptions confirm this was a classic stored XSS vulnerability in comment author name handling.
