Description
The Otter Blocks WordPress plugin before 3.2.8 does not enforce its block visibility conditions when a published post is rendered through the WordPress REST API, allowing unauthenticated users to read block content that the site owner restricted to specific roles, logged-in users, the post author, categories or tags, or (on the Pro tier) Stripe purchasers.
