At a glance

CVE-2024-2541 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Popup Builder WordPress plugin, affecting versions <= 4.3.6. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.3.7; sites on affected versions should update now. Disclosed August 2024, reported by Tim Coen.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Popup Builder <= 4.3.6 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Popup Builder the fix is 4.3.7: builds <= 4.3.6 are affected, anything from 4.3.7 onward is not.

Remediation

Update to version 4.3.7, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Popup Builder 4.3.7 closes this, and updating the plugin is the step that ends it.
