CVE-2026-7526: CWE-200 Exposure of Sensitive Information to an Unauthorized Actor in smub PDF Embedder
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
Technical Summary
The smub PDF Embedder plugin for WordPress contains a sensitive information exposure vulnerability (CWE-200) in all versions up to and including 4.9.3. Authenticated users with contributor or higher privileges can leverage the enqueue_block_assets function to access configuration data. If the premium add-on is installed and contains a saved license key, this key is exposed. Otherwise, only non-sensitive viewer configuration values are accessible. The vulnerability has a CVSS 3.1 base score of 4.3, indicating medium severity. There is no vendor advisory or patch currently available, and the plugin is not a cloud service, so remediation depends on the vendor releasing an update.
Potential Impact
An attacker with contributor-level access or higher can extract configuration data from the plugin. This includes exposure of the premium add-on license key if installed, which could potentially be used for unauthorized premium feature access or license misuse. For Lite-only installations, the impact is limited to exposure of non-sensitive configuration parameters. There is no indication of impact on integrity or availability. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit contributor-level access to trusted users only to reduce risk. Monitor for updates from the smub plugin vendor regarding a security patch addressing this vulnerability.
