Summary
The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.2.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit requires the plugin to be in its normal connected state (cdn_key and cdn_secret configured) with the image replacer enabled, which is the default post-setup configuration; the stored payload bypasses all WordPress comment sanitization filters because it contains no HTML metacharacters at storage time — the characters are produced only by Optimole's own decoder at render time.
