## Affected

- Unknown Image Optimizer, Resizer and CDN: fixed in 6.8.1

## Description

The Image Optimizer, Resizer and CDN WordPress plugin before 6.8.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

## What to do

- Check your stack: if you ship or depend on Unknown Image Optimizer, Resizer and CDN, upgrade to a fixed version (6.8.1) per the references below.
