Summary
The WordLift – AI powered SEO – Schema plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.54.10 via the JSON-LD REST API endpoints. This is due to the plugin registering the /wordlift/v1/jsonld/ routes (jsonld/{id}, jsonld/http/{item_id}, jsonld/post-meta/{meta_key}, jsonld/meta/{meta_key}, and jsonld/{post_type}/{post_name}) with a permission_callback of '__return_true' and the downstream converter retrieving the post via get_post() without verifying the post status or the requesting user's capabilities. This makes it possible for unauthenticated attackers to read the title, content/description, author, publication and modification dates, word count, comment count, and other metadata of private, draft, and pending posts by enumerating post IDs, bypassing WordPress core access controls.
