## What it looks like

A comment carries script-capable content that runs when staff view it.

## Why it matters

The script can act in the staff member's browser and may expose session data.

## What to check

Review comment rendering and escape untrusted output in its HTML context.

## 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/).
