Airtable

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, airtable.com is more exposed to malicious JavaScript, redirected forms, hijacked payments and clickjacking.

Missing 6

• Content-Security-Policy 0 of 25

  Tells the browser which scripts may run on the page, where its forms may submit, and where it may send data.

  Without it: This is the main defence against malicious JavaScript. If an attacker gets any script onto the page (through a bug, a compromised analytics tag, chat widget or ad, or a poisoned package), the browser runs it with the signed-in user's full access. It can capture what they type, quietly point a sign-in or checkout form at the attacker's server, and skim card numbers as they are entered. A strict policy blocks scripts it does not list, and its form-action and connect-src rules leave stolen data nowhere to go.

• 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.

• Frame protection 0 of 10

  X-Frame-Options or the CSP frame-ancestors directive: decides which sites may show this one inside a frame.

  Without it: Clickjacking. Another site loads the product invisibly in a frame and lines its real buttons up under something the user wants to click, so a signed-in user approves a payment, changes their account email or grants access without seeing it.

• Cross-Origin-Opener-Policy 0 of 5

  Cuts the link between the product's window and windows opened by, or opening, other sites.

  Without it: A page that opens the product keeps a handle on its window and can later redirect it to a look-alike sign-in or payment page (tab-nabbing) while the user thinks they are still on the real site. It is also part of the isolation browsers need to defend against Spectre-style attacks.

• 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.

• No version disclosure 0 of 5

  Keeps the Server and X-Powered-By headers from announcing exact software versions.

  Without it: A header like "nginx/1.18.0" or "PHP/7.4" tells an attacker which known vulnerabilities to try, and flags possibly unpatched software to every automated scanner on the internet.
