Miggo AIRoot Cause Analysis

The vulnerability stems from improper sanitization of user-supplied data in the assignee selection component. The code at line 263 of gogs.js shows UI updates using .html() with user-controlled input (full_name). When an admin selects a malicious user as assignee, the unescaped JavaScript payload in the user's name field executes due to unsafe HTML insertion methods. This matches the PoC description where XSS in the assignee selection leads to privilege escalation.
