The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'a' (above_fold_images) parameter in all versions up to, and including, 4.2.10 due to insufficient input sanitization and output escaping.
