Security observations what the browser noticed while this ran — not a penetration test
| Severity | Finding | What to do |
|---|---|---|
| medium | The application is served over plain HTTP http://127.0.0.1:8000/demo/ is not HTTPS, so anything typed into it travels the network in the clear and can be modified in transit. |
On an isolated lab network this may be a deliberate choice -- if so, note it and move on. Anywhere else, terminate TLS in front of the application. |
| info | No document response was observed The test never loaded a top-level page from the target, so its headers could not be checked. |
Have the test call page.goto(ctx.base_url) at least once. |
| info | Cookie 'csrftoken' is readable by JavaScript (expected) This looks like a CSRF token, which the page's own JavaScript has to read in order to send it back. HttpOnly would break that. Nothing to do -- listed so you know it was checked and not missed. |
No action. Do check that SESSION cookies are HttpOnly. |
All of these appear together on the Security page.
