## What it looks like

A custom REST route returns private records or performs changes for a signed-out visitor.

## Why it matters

Data may leak or site state may change without an account.

## What to check

Inventory custom routes and verify their permission callbacks reject anonymous requests where access is private.

## 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 REST endpoint permissions](https://developer.wordpress.org/rest-api/extending-the-rest-api/adding-custom-endpoints/).
