Summary

ajenti through v2.2.13 has a clickjacking weakness in the browser-facing login and administrative UI. In ajenti-core/aj/http.py, the core HTTP response path initializes an empty header list, forwards handler-added headers verbatim, and finalizes responses through WSGI start_response() without adding anti-framing protections such as X-Frame-Options or a Content-Security-Policy frame-ancestors restriction.
