Description
The Otter Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure via the Dynamic Image feature in all versions up to, and including, 3.2.9, due to a missing authorization check when dynamic image URLs are resolved during block rendering for an arbitrary context post or product ID. This makes it possible for authenticated attackers, with contributor-level access and above, to reveal images of private or draft posts they cannot access, such as featured images and author avatars, for example by rendering their own draft through the REST API.
