FKIE_CVE-2026-7526

Vulnerability from fkie_nvd - Published: 2026-05-28 09:16 - Updated: 2026-05-28 13:45
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
Summary
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.
