Name of the Vulnerable Software and Affected Versions:

ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress versions through 3.10.3

Description:

The ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress is susceptible to Stored Cross-Site Scripting via the API URL Setting due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level access to inject arbitrary web scripts into pages, which will execute when a user accesses the injected page. This issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations:

Update ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress to a version later than 3.10.3.
