Checks

Do the forms on your site send data over HTTPS?

By Mark KashefPublished October 8, 2026

The form destination check reads where each form on a page says it sends its data, and flags any plain http destination. No form is filled in or submitted.

What does this check look at?

It looks at whether the forms on a page say they send their data to a plain HTTP address. Lockpick never sends attack payloads, fills in your forms or tries passwords.

Pulse and Deep scans both run it.

What does a result mean?

What the report showsWhat it meansWhat to do
PassEvery form read declares an https destination.Nothing.
AttentionA form declares a plain http destination.Point it at an https address.
Not testedForms could not be read completely, or the page builds them in the browser.Nothing to act on.

No form is filled in or sent, so validation, sign-in logic and cross-site request forgery defences are not tested. Scripts can change where a form really sends, so the declared destination is what the page says, not what happens on submit. A clean result means nothing was found in what the scan read. It does not prove the problem is absent from parts the scan never sees.

How serious is a finding?

Treat this as a hardening gap. It makes an attacker’s job easier but gives them no path of its own, so fix it after anything more direct. Confidence starts low, because it is inferred from headers or declarations rather than shown directly. The report lists what to fix by how directly someone could use it, not by the severity label.

What does a confirmed finding have to show?

Which standards does it relate to?

StandardReference
OWASP Top TenA04:2025 Cryptographic Failures
CWECWE-319
ASVSv5.0.0-12.2.1

Each one is a related control, not a verification. A scan sees what anyone online can see, so it never proves a whole requirement is met.

Fix it with your AI

Ask your AI to check the declared destination and the code that really submits the form.

Fix prompt for any coding agent
Find every form on my site and check where it submits: the action attribute and any JavaScript submit handler. Make sure each one posts to an https:// address on my own site or my form provider. Change any http:// destination to https://, and tell me if a form sends data to another company I did not expect.

How to check

Say Atlas, our example app at atlas.example, has a newsletter form whose action still points at an old http address. The check flags it, and changing the address to https fixes it.

The free quick check covers this on your homepage with no account, and a Pulse scan from your account adds your scripts and public records. Pulse or Deep explains the difference.

Questions people ask

Does this check my login form for other problems?

No. It only reads the declared destination. Password-specific problems, such as a password sent in the address, have their own check.

Why is it marked not tested on my React app?

If forms only exist after scripts run, the HTML the scan read may not contain them. The report says so rather than guessing.

Lockpick is a security scanner for vibe-coded apps. It checks what your live site exposes and what a GitHub repo or AI skill would do before you install it, then gives you a fix prompt for Lovable, Bolt, Replit, Cursor or Claude Code.

Lockpick assesses public pages you are authorized to test, and public GitHub code it never runs.
