Security review

Written by gpt-4o-mini from 16 checks over the crawl

The website lacks important security headers, which increases vulnerability to interception and attacks. Key fixes include implementing HTTP Strict Transport Security, a Content Security Policy, and secure cookie flags. Additionally, one JavaScript library has known vulnerabilities that need upgrading.

  • 0 high
  • 6 medium
  • 2 low
  • 1 info
  1. 1

    Missing HTTP Strict Transport Security (HSTS) HeaderMedium

    Why it matters: Without HSTS, initial requests without HTTPS can be intercepted.

    Fix: Add the header: Strict-Transport-Security: max-age=31536000; includeSubDomains.

    Evidence: HTTP Strict Transport Security

  2. 2

    No Content Security Policy (CSP)Medium

    Why it matters: Lack of CSP allows unauthorized sources to load scripts and resources.

    Fix: Implement a CSP header, e.g., Content-Security-Policy: default-src 'self'; script-src 'self'.

    Evidence: Content Security Policy

  3. 3

    Missing X-Frame-Options HeaderMedium

    Why it matters: Without this header, the site is vulnerable to clickjacking attacks by being embedded in frames.

    Fix: Add the header: X-Frame-Options: DENY.

    Evidence: Clickjacking protection

  4. 4

    Cookies Lack Security FlagsMedium

    Why it matters: Cookies without protective flags are vulnerable to being accessed by unauthorized scripts.

    Fix: Set cookies with flags: HttpOnly, Secure, SameSite=Lax.

    Evidence: Cookie flags

  5. 5

    Vulnerable JavaScript LibraryMedium

    Why it matters: jQuery 3.2.1 has known vulnerabilities that could be exploited.

    Fix: Upgrade jQuery to at least version 3.5.0.

    Evidence: Vulnerable JavaScript libraries

  6. 6

    Leaked Google API KeyMedium

    Why it matters: Exposing keys can lead to unauthorized usage and costs.

    Fix: Restrict the key via Google Cloud console and consider removing it from the page.

    Evidence: Keys and secrets in page code

  7. 7

    Missing X-Content-Type-Options HeaderLow

    Why it matters: This can lead to MIME sniffing attacks where a browser misinterprets file types.

    Fix: Add the header: X-Content-Type-Options: nosniff.

    Evidence: MIME sniffing protection

  8. 8

    Missing Referrer-Policy HeaderLow

    Why it matters: Without this header, sensitive URLs can be leaked to external sites when visitors navigate away.

    Fix: Add the header: Referrer-Policy: no-referrer.

    Evidence: Referrer policy

  9. 9

    Missing Permissions-Policy HeaderInfo

    Why it matters: This can limit the capabilities of potential injected scripts on the site.

    Fix: Add the header: Permissions-Policy: geolocation=(), microphone=().

    Evidence: Permissions policy
