Description
The Otter Blocks plugin for WordPress is vulnerable to a block visibility conditions bypass in all versions up to, and including, 3.2.7 due to block conditions being skipped for every REST API request. This makes it possible for unauthenticated attackers to retrieve, through REST responses that render block content, blocks that the site owner restricted with Otter block conditions (for example, blocks shown only to logged-in users).
