## What it looks like

A plugin registers a route that discloses internal data or actions more broadly than intended.

## Why it matters

Remote callers may reach functionality that was assumed to be private.

## What to check

List plugin routes and review the data returned and the permission callback for each one.

## 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/).
