CVE-2026-7526
Deferred Deferred - Pending Action
Sensitive Information Exposure in PDF Embedder WordPress Plugin

Publication date: 2026-05-28

Last updated on: 2026-05-28

Assigner: Wordfence

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.

Compliance Impact

This vulnerability allows authenticated attackers with contributor-level access and above to extract configuration data from the PDF Embedder plugin for WordPress. When the premium add-on is installed and has a saved license key, sensitive information such as the license key may be exposed. On Lite-only installations, the exposed data is limited to non-sensitive viewer configuration values.

Exposure of sensitive information like license keys could potentially impact compliance with data protection standards such as GDPR or HIPAA, which require protection of sensitive data and prevention of unauthorized access. However, the vulnerability does not appear to expose personal user data directly, but rather configuration and license information.

Therefore, organizations using this plugin should consider the risk of sensitive configuration data exposure in their compliance assessments and apply appropriate mitigations to maintain compliance with relevant standards.

Executive Summary

The PDF Embedder plugin for WordPress has a vulnerability in all versions up to and including 4.9.3. This vulnerability allows authenticated users with contributor-level access or higher to extract configuration data through the enqueue_block_assets function.

If the premium add-on is installed and has a saved license key, this key can be exposed. For installations using only the Lite version, the exposed data is limited to non-sensitive viewer configuration values such as width, height, toolbar settings, usage tracking, and plan.

Impact Analysis

This vulnerability can lead to sensitive information exposure, particularly the license key if the premium add-on is installed. An attacker with contributor-level access could extract this key, potentially leading to unauthorized use or distribution of the premium features.

Even without the premium add-on, configuration data such as viewer settings and usage tracking information can be exposed, which might reveal some operational details about the website.
