Security headers: C, 55 out of 100
Number 60 of 116 in the ranking. Missing 4 of the 9 headers we check.
Below the B minimum (70/100) in our RFP clause. A buyer using it would ask for a dated fix for each missing header.
With these headers missing, blender.org is more exposed to man-in-the-middle attacks, malicious JavaScript, redirected forms and hijacked payments.

-
Strict-Transport-Security 0 of 20
Tells browsers to use HTTPS for this domain, every time, without trying plain HTTP first.
Without it: The site is open to man-in-the-middle attacks. The first request a user makes (typing the domain, following an old http:// link) can go out unencrypted, and anyone on the same network, such as café, hotel or airport Wi-Fi, can intercept it before the redirect to HTTPS. From there they can read passwords, session cookies and card numbers, serve a fake sign-in page, or inject their own JavaScript into the real one.
-
X-Content-Type-Options 0 of 10
Stops the browser guessing a file's type instead of trusting the type the server declared.
Without it: A file uploaded as an image or plain text can be reinterpreted as HTML or script and run inside the product's own origin: malicious JavaScript delivered through a harmless-looking upload feature.
-
Permissions-Policy 0 of 10
Switches off browser features the product does not use, such as camera, microphone, location and payments, for the page and anything embedded in it.
Without it: Any script or iframe on the page, including third-party ads and chat widgets, can ask the user for camera, microphone or location access under the vendor's name.
-
Cross-Origin-Resource-Policy 0 of 5
Tells browsers which sites may load this site's resources.
Without it: Other sites can pull the product's responses into their own pages, which makes side-channel leaks of what a signed-in user can see easier.
