Security review
Written by gpt-4o-mini from 16 checks over the crawlYour website has several security weaknesses that need attention. Key issues include missing Clickjacking and Referrer policies, which leave your site open to attacks. Additionally, certain cookie protections are lacking, which could expose sensitive user data. Addressing these items will greatly enhance your site's security.

- 2 medium
- 1 low

- 1
Missing Clickjacking ProtectionMedium
Why it matters: Without X-Frame-Options or CSP frame-ancestors, your pages can be embedded in frames and exploited.
Fix: Add the X-Frame-Options header with the value 'DENY' or a Content Security Policy to prevent framing.
Evidence: Clickjacking protection
- 2
Cookies Lacking Secure AttributesMedium
Why it matters: Missing HttpOnly, Secure, or SameSite flags can allow script attacks or send cookies over unencrypted connections.
Fix: Set the cookie flags: 'HttpOnly', 'Secure', and 'SameSite=Lax' for your cookies.
Evidence: Cookie flags
- 3
Missing Referrer PolicyLow
Why it matters: Without a Referrer-Policy, sensitive URL information may be leaked to external sites.
Fix: Add the Referrer-Policy header with the value 'no-referrer' or an appropriate option.
Evidence: Referrer policy
- 4
Missing Permissions PolicyInfo
Why it matters: Absence of a Permissions-Policy can allow unwanted use of browser features like camera or geolocation by injected scripts.
Fix: Include the Permissions-Policy header with appropriate directives.
Evidence: Permissions policy
What the checks found
- FoundClickjacking protectionMedium
1072 of 3456 HTML pages send x-frame-options. Without X-Frame-Options (or a CSP frame-ancestors directive) the pages can be embedded in a frame on another site and overlaid with invisible controls.

- https://ntcore.io.vn/contact/ → no referrer-policy
- FoundPermissions policyInfo
No HTML page sends permissions-policy. A Permissions-Policy header turns off browser features the site does not use (camera, microphone, geolocation), limiting what an injected script could do.

- https://ntcore.io.vn/contact/ → no permissions-policy
- FoundCookie flagsMedium
1 of 2 cookies are missing protective flags. Without HttpOnly a script can read the cookie; without Secure it travels over plain HTTP; without SameSite it is sent on cross-site requests.
- wordpress_test_cookie (set by https://ntcore.io.vn/ths/?redirect_to=https%3A%2F%2Fntcore.io.vn%2Frepair-pdf-o…) lacks SameSite
- NoteThird-party scripts
Scripts run from 3 other domains without Subresource Integrity, so a compromise of any of them changes what runs on this site. (Tag managers and analytics rarely support SRI; a Content-Security-Policy that names these hosts is the usual control.)
- www.googletagmanager.com (40 script tags)
- pagead2.googlesyndication.com (40 script tags)
- cdnjs.cloudflare.com (1 script tag)
- NoteSensitive paths in robots.txt
robots.txt lists 2 paths that look private. robots.txt is public and does not restrict access, so it doubles as a map for anyone probing the site; those paths need real access control.
- Disallow: /wp-admin/
- Disallow: /cgi-bin/
