## What it looks like

Builder JavaScript inserts untrusted URL or content data into the page unsafely.

## Why it matters

The browser executes script even if the server response is static.

## What to check

Review client-side rendering and avoid treating untrusted text as HTML.

## 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 [WordPress output escaping](https://developer.wordpress.org/apis/security/escaping/).
