Wordpress Alert: Checkout-field upload vulnerabilities

What it looks like

A checkout extension accepts files without suitable type or authorization checks.

Why it matters

Customer-supplied files may become a code or data exposure route.

What to check

Review checkout extensions and their upload configuration and advisories.

Documentation

This is an exploit pattern to check in installed components, not a claim that every WordPress site has this flaw. Confirm the product and version against its advisories before treating a site as affected. See OWASP file upload guidance, WooCommerce security FAQ.
