CVE-2024-2541: popup builder vulnerability

What is known

The Popup Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.3.6 via the Subscribers Import feature. This makes it possible for unauthenticated attackers to extract sensitive data after an administrator has imported subscribers via a CSV file. This data may include the first name, last name, e-mail address, and potentially other personally identifiable information of subscribers.

Business impact

Successful exploitation of CVE-2024-2541, a medium vulnerability (CVSS 5.3) affecting popup builder, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether popup builder is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
