Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-200.

Summary

The Otter Blocks WordPress plugin from 3.1.1 before 3.2.8 does not correctly check whether a post is publicly readable before returning its data through a REST API endpoint. Any post with the published status is treated as public, so an unauthenticated user can 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. This is an exposure of sensitive information (CWE-200) that requires no authentication.
