The Qubely – Advanced Gutenberg Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.8.13 via the 'qubely_get_content'. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive private, pending, scheduled, password-protected, draft, and trashed post data.
The product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected.
