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.

AI Analysis

Impact

The PDF Embedder plugin for WordPress contains a vulnerability that permits authenticated users possessing contributor-level access or higher to retrieve configuration data through the enqueue_block_assets hook. The flaw enables extraction of license keys when the premium add-on is installed, while on Lite-only installs only non‑sensitive viewer configuration parameters are exposed. This constitutes a Sensitive Information Exposure (CWE‑200) with a CVSS score of 4.3, indicating a moderate risk to confidentiality.

Affected Systems

The affected product is the PDF Embedder WordPress plugin from smub, versions up to and including 4.9.3. No other version or vendor information is provided.

Risk and Exploitability

Exploitation requires an authenticated WordPress account with contributor permissions or higher and relies on the block editor triggering the enqueue_block_assets routine. The EPSS score is not available and the vulnerability is not listed in the K‑CAL KEV catalog. Therefore, while the likelihood of exploitation may be modest, the impact remains that an attacker could obtain configuration data or premium license keys, potentially aiding further attacks on the site.
