Description
The Solace Extra plugin for WordPress is vulnerable to unauthorized access in all versions up to 1.7.0. This is due to missing post-status and capability checks on the Site Builder part rendering endpoint, which previously served any solace-sitebuilder post regardless of publication status or user identity. This makes it possible for unauthenticated attackers to read the full rendered content of non-published (draft, pending, private, or trashed) Site Builder parts without authentication.
