Embed Google Photos album < 2.2.1 - Authenticated (Contributor+) Server-Side Request Forgery

Description

The Embed Google Photos album plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.2.0 via the Pavex_embed_google_photos_album class. This makes it possible for authenticated attackers, with contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
