Forms over HTTPS

Form action URLs must not post to http://.

Pass condition in our engine: No form action starts with http://.

1. Problem description

A login or checkout form that posts to HTTP sends secrets in cleartext even if the page itself is HTTPS. We look at action attributes starting with http://.

2. Most common causes

  • Absolute http:// action copied from an old environment.
  • A payment vendor still on HTTP (replace them).

3. How to fix it

  1. Use https:// or relative actions.
  2. HSTS plus mixed-content fixes as backup.
