    "title": "Stored XSS via SVG Upload",
    "summary": "SQLBot is an intelligent Text-to-SQL system based on large language models and RAG. Prior to 1.9.0, an authenticated uploader can submit an image/svg+xml assistant UI logo through PATCH /api/v1/system/assistant/ui, and SQLBot stores the SVG without sanitizing or validating embedded active content. SQLBot later serves the file inline from the same application origin through GET /api/v1/system/assistant/picture/{filename}. When another user loads that generated resource, JavaScript embedded in the SVG executes in the SQLBot web application context, resulting in stored cross-site scripting with access to data and actions available to the victim's session. This issue is fixed in version 1.9.0.",
