## What it looks like

A cache stores personalized or restricted output as a public response.

## Why it matters

One visitor may receive another user's content.

## What to check

Check cache rules for logged-in sessions, private routes, and preview URLs.

## 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 web cache security guidance](https://cheatsheetseries.owasp.org/cheatsheets/Web_Cache_Security_Cheat_Sheet.html).
