Vulnerability from github – Published: 2026-07-07 00:30 – Updated: 2026-07-09 18:31

Details

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.

Severity

5.4 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
