Critical 1

CriticalYour server's source code is published as a static file

Who can exploit this: Anyone on the internet

example.com: server source code is served as static files (/app.js) -- anything saved in that folder (uploads, exports, backups) is downloadable by name 1 file with server-only code

What it means

Files like server.js are downloadable, which means the folder your server runs from is also the public web folder. Anyone can read your backend code, and anything the app saves in that folder (uploads, exports, backups, .env) is downloadable by name.

How to fix

Serve static files from a dedicated folder (e.g. public/ or dist/), never from the project root.
Check what else lives in that folder (.env, uploads, exports) and rotate any secret.
Run the recheck.

HighPlain HTTP does not redirect to HTTPS

Who can exploit this: Someone on the same network as your user (public Wi-Fi)

example.com: plain HTTP is served without redirecting to HTTPS (/ /login)

What it means

Visitors who type your address without https:// can be served an unencrypted page, which an attacker on the network can tamper with.

How to fix

Turn on 'Force HTTPS' / 'Always use HTTPS' in your host or CDN, or add a 301 redirect from http:// to https://.
Add HSTS (see the related finding).
Run the recheck.

MediumNo Content-Security-Policy

Who can exploit this: An attacker who manages to inject a script

Site: no Content-Security-Policy (no defence in depth against injected scripts)

What it means

A Content-Security-Policy tells the browser which scripts may run. Without one, any script an attacker manages to inject (through a comment, a profile field or a compromised library) runs with full access to your users' sessions.

How to fix

Start with a policy like: default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'; then add the domains your app really loads from (Supabase, analytics, fonts).
Try it first as Content-Security-Policy-Report-Only, fix what breaks, then switch to enforcing.

Low 4

LowDMARC is monitor-only

Who can exploit this: Anyone sending email

DMARC is monitor-only (p=none): forged @example.com email is still delivered -- move to p=quarantine, then p=reject

What it means

Your DMARC policy is p=none, so forged email is still delivered.

How to fix

Move to p=quarantine, then p=reject once your legitimate senders pass.

LowHosting control panel login faces the internet

Who can exploit this: Anyone on the internet

Hosting control panel login reachable from the internet: cPanel (:2083, 200), WHM (:2087, 200), Webmail (:2096, 200) -- use a strong password and 2FA, or limit it to your IPs

What it means

The login page of your hosting control panel (cPanel, Plesk…) is reachable by anyone, so its password is the only thing protecting your whole server.

How to fix

Use a long unique password and enable two-factor authentication.
If your host allows it, restrict the panel to your IP addresses.

LowNo Referrer-Policy

Who can exploit this: Attackers mapping your site for weak spots

Site: no Referrer-Policy

What it means

Without a Referrer-Policy, full page URLs (which can contain IDs or tokens) may be sent to other sites your pages link to.

How to fix

Send Referrer-Policy: strict-origin-when-cross-origin.
Run the recheck.

For your information 9

InfoA firewall blocked some file checks

Who can exploit this: Nobody directly; good practice

A server-side filter (406, e.g. ModSecurity) blocked 2 probe(s) -- those files were not tested

What it means

A web application firewall answered 406 to some probes, so those paths were not tested. That is fine; it just limits what this scan could see.

InfoInline scripts without a nonce

Who can exploit this: Nobody directly; good practice

Page has 3 inline script(s) without a nonce: a strict CSP needs nonces or hashes for them

What it means

Not a vulnerability by itself, but a strict Content-Security-Policy will need nonces or hashes for these scripts.

InfoNo CAA record

Who can exploit this: Nobody directly; good practice

No CAA record (any certificate authority may issue for example.com)

What it means

A CAA DNS record limits which certificate authorities may issue certificates for your domain. Optional hardening.

How to fix

Add a CAA record for the authority you use, e.g. 0 issue "letsencrypt.org".

InfoNo Permissions-Policy

Who can exploit this: Nobody directly; good practice

Site: no Permissions-Policy

What it means

A Permissions-Policy switches off browser features (camera, microphone, location) your site doesn't use, limiting what an injected script could do.

How to fix

Send e.g. Permissions-Policy: camera=(), microphone=(), geolocation=() for features you don't use.

The app appears to keep its session token in localStorage (readable by any script on the page; CSP matters more)

What it means

Anything in localStorage can be read by any script on the page. If a script is ever injected, it can steal sessions. This is common (Supabase does it by default) and makes a strong CSP more important.

Keep a strict Content-Security-Policy.
