A stored cross-site scripting vulnerability has been identified in Assafelovic GPT-Researcher versions through 3.4.3. The issue resides in the Report API, specifically within the file backend/server/app.py. This vulnerability allows an attacker to inject arbitrary HTML and JavaScript into research reports via the unauthenticated POST and PUT endpoints of the Report API. The injected payload is stored on the server and rendered unsanitized in the Next.js frontend, executing the attacker's JavaScript in the victim's browser.
Sanitize input on the backend before storing reports, enable sanitization in the frontend when rendering markdown, and consider adding authentication to the Report API.
