CVE-2026-109934
Otter Blocks 3.1.1 - 3.2.7 - Unauthenticated Non-Public Content Disclosure via REST API
Medium 5.3
The Otter Blocks WordPress plugin before 3.2.8 does not correctly determine whether a post is publicly readable before returning its data through a REST API endpoint, treating any post with the published status as public, allowing unauthenticated users to read manual excerpts of password-protected posts, the content and titles of non-public post types, and, on WooCommerce sites, coupon codes and their descriptions.
