CVE-2024-4213 identifies a vulnerability in the levelfourstorefront Shopping Cart & eCommerce Store plugin for WordPress, affecting all versions up to 5.6.4. The vulnerability is categorized under CWE-922, which pertains to insecure storage or exposure of sensitive information. Specifically, the order report functionality in the plugin improperly exposes sensitive customer data such as payment details, shipping and billing addresses, and other personally identifiable information (PII). This exposure can be exploited by unauthenticated attackers remotely without any user interaction or privileges, making it a critical privacy concern. The vulnerability does not impact data integrity or availability but compromises confidentiality. The CVSS 3.1 base score of 5.3 reflects a medium severity level due to the ease of exploitation (network vector, no privileges, no user interaction) but limited impact scope. No patches or fixes have been officially released at the time of this report, and no known exploits have been observed in the wild. The vulnerability poses a significant risk to organizations using this plugin, especially those handling sensitive customer data, as it could lead to data breaches, regulatory penalties, and loss of customer trust. The plugin is widely used in WordPress e-commerce deployments, increasing the potential attack surface globally.

The primary impact of CVE-2024-4213 is the unauthorized disclosure of sensitive customer information, including payment details and PII. This can lead to privacy violations, identity theft, financial fraud, and regulatory non-compliance (e.g., GDPR, CCPA). Organizations may suffer reputational damage, loss of customer trust, and potential legal consequences. Since the vulnerability allows unauthenticated remote access, attackers can exploit it at scale, increasing the risk of mass data exposure. Although the vulnerability does not affect system integrity or availability, the confidentiality breach alone is significant for e-commerce businesses. The exposure of payment information could also facilitate secondary attacks such as phishing or account takeover. The lack of authentication or user interaction requirements lowers the barrier for exploitation, making it attractive for opportunistic attackers. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge once the vulnerability becomes widely known.

1. Immediately restrict access to the order report functionality by implementing IP whitelisting or requiring authentication to prevent unauthenticated access. 2. Monitor web server and application logs for unusual or unauthorized access attempts to order report endpoints. 3. Disable or remove the levelfourstorefront Shopping Cart & eCommerce Store plugin if feasible until a patch is available. 4. Regularly check for updates from the vendor and apply patches promptly once released. 5. Implement web application firewall (WAF) rules to block suspicious requests targeting the order report functionality. 6. Conduct a thorough audit of exposed data to assess potential leakage and notify affected customers if necessary. 7. Review and enhance data storage and access controls within the e-commerce environment to minimize sensitive data exposure. 8. Educate staff and customers about potential phishing or fraud attempts that may arise from leaked data. These measures go beyond generic advice by focusing on access control, monitoring, and proactive data protection specific to this vulnerability.
