Create WordPress plugin vulnerabilities

The Create plugin for WordPress in all versions up to and including 2.5.3 is vulnerable to generic SQL Injection via the 'order' parameter due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query. The vulnerable advanced-filter SQL branch is only entered when at least one of the following parameters is present: linked_posts, created_after, created_before, missing_fields, post_id, a comma-separated type value, or exclude_type.

The Create plugin for WordPress in all versions up to and including 2.5.3 is vulnerable to generic SQL Injection via the 'order_by' parameter due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query. The REST endpoint permission callback defaults to the publish_posts capability, meaning any Author-level user or above can reach the vulnerable code path without any additional preconditions.

The Create WordPress plugin before version 2.5.4 does not perform an authorization check before rendering content over one of its public REST API routes, and that route additionally publishes the requested content as a side effect, allowing unauthenticated attackers to read unpublished content and make it publicly available.
