Description
The PDF Embedder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.9.3 via the enqueue_block_assets. This makes it possible for authenticated attackers, with contributor-level access and above, to extract configuration data. License key exposure occurs when the premium add-on is also installed and has saved a key; on Lite-only installations, the exposed data is limited to non-sensitive viewer configuration values such as width, height, toolbar settings, usage tracking, and plan.
