Website check
walmart.com
In plain English
Walmart.com scored B (82/100) on this passive check. All six findings are rated low, so this is a solid baseline with some hardening left to do. The first thing to fix is the cookie settings: add the Secure and SameSite flags so cookies are only sent over HTTPS and are not sent along with cross-site requests. Visitors do not need to take any action, and this check alone does not suggest their data is at immediate risk.
Cookies sent without the Secure flag
These cookies can travel over plain HTTP, where anyone on the same network can read them.
How to fix: Add the Secure attribute to every cookie the site sets.
Cookies: isoLoc, ak_bmsc
Cookies without a SameSite setting
Without SameSite, some browsers send these cookies along with requests started by other sites, which helps cross-site request forgery.
How to fix: Add SameSite=Lax (or Strict) to cookies. Use SameSite=None only together with Secure, and only when truly needed.
Cookies: isoLoc, ak_bmsc
Content Security Policy does not limit scripts
The policy has no script-src or default-src rule, so it does nothing to stop injected scripts.
How to fix: Add a script-src (or default-src) rule that lists only the sources the site uses.
frame-ancestors 'self' *.wal.co *.walmart-customcards.com *.walmart.com:* *.walmart.net *.walmartimages.com www.samsclub...
No X-Content-Type-Options header
Browsers may guess file types, which can let an uploaded file run as a script.
How to fix: Send X-Content-Type-Options: nosniff.
No Referrer-Policy header
Some browsers may pass full page addresses, including any private details in them, to other sites visitors go to.
How to fix: Send Referrer-Policy: strict-origin-when-cross-origin (or stricter).
Third-party scripts without integrity checks
The page loads scripts from other companies' servers without a fingerprint check. If one of those servers is hacked, the attacker's code runs on this site.
How to fix: Add integrity and crossorigin attributes to fixed-version third-party scripts, or host the files yourself.

This check is passive and automated: it reads only what a normal visit can see and can miss problems a full audit would find. A good grade is not a guarantee. If you run this site and something here is wrong, the fix steps are a starting point, not a substitute for your host or a security professional.
