The PixelYourSite Pro – Your smart PIXEL (TAG) Manager plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 12.5.0.1 via the scan_video. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. The SSRF is blind because fetched response bodies are only parsed internally for YouTube/Vimeo patterns and are never returned to the attacker.
