## Description

The Otter Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure via the otter/v1/dynamic REST endpoint in all versions up to, and including, 3.2.7 due to an insufficient permission check that treated any published post as viewable. This makes it possible for unauthenticated attackers to retrieve the content of password-protected posts and of post types that are not publicly viewable.
