Summary
New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to version 0.10.8-alpha.9, a potential unsafe operation occurs in component `MarkdownRenderer.jsx`, allowing for Cross-Site Scripting(XSS) when the model outputs items containing `<script>` tag. Version 0.10.8-alpha.9 fixes the issue.
