Description

The ShortPixel Adaptive Images – WebP AVIF CDN Image Optimization plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the API URL Setting in all versions up to and including 3.10.3 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled.
