CVE-2025-62997 is a vulnerability identified in the WP EasyCart plugin developed by levelfourdevelopment, affecting all versions up to and including 5.8.11. The issue is characterized as an 'Insertion of Sensitive Information Into Sent Data' vulnerability, which allows an attacker to retrieve embedded sensitive data transmitted by the plugin. The vulnerability does not require any authentication or user interaction, and can be exploited remotely over the network (AV:N/AC:L/PR:N/UI:N). The CVSS v3.1 base score is 5.3, indicating a medium severity level primarily due to the confidentiality impact (C:L) without affecting integrity or availability. The root cause likely involves the plugin including sensitive information such as credentials, tokens, or personal data within outgoing data streams, which can be intercepted or accessed by an attacker. No known exploits have been reported in the wild as of the publication date (December 9, 2025). The vulnerability affects e-commerce websites using WP EasyCart, potentially exposing customer or business-sensitive information. The lack of a vendor patch link suggests that remediation may not yet be available, requiring users to implement temporary mitigations or monitor for updates. The vulnerability was reserved in late October 2025 and published in December 2025 by Patchstack, a known security researcher group specializing in WordPress vulnerabilities.

For European organizations, the exposure of sensitive information through WP EasyCart can have significant consequences. E-commerce platforms often handle customer personal data, payment details, and transaction information, all of which are subject to strict data protection regulations such as the GDPR. Unauthorized disclosure of such data can lead to regulatory fines, reputational damage, and loss of customer trust. The vulnerability's ease of exploitation (no authentication or user interaction required) increases the risk of automated scanning and data harvesting by attackers. Additionally, the confidentiality breach could facilitate further attacks such as identity theft, fraud, or targeted phishing campaigns. Organizations relying on WP EasyCart for their online sales may experience operational disruptions if they need to take the plugin offline to mitigate risk. The impact is heightened in sectors with sensitive customer data or high transaction volumes, including retail, finance, and healthcare e-commerce. Given the medium severity, the threat is serious but not critical, allowing some time for mitigation before exploitation becomes widespread.

1. Monitor official WP EasyCart channels and Patchstack advisories for an official security patch and apply it immediately upon release. 2. Until a patch is available, consider disabling or uninstalling WP EasyCart if feasible, or restrict its network exposure using firewall rules to limit external access. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests that may attempt to exploit this vulnerability or intercept sensitive data. 4. Review and sanitize all outgoing data from the plugin to ensure no sensitive information is unnecessarily included in transmitted data streams. 5. Conduct a thorough audit of the plugin’s configuration and usage to minimize sensitive data exposure, including disabling debug or verbose logging features that might leak data. 6. Educate staff and users about the risk of phishing or social engineering attacks that could leverage leaked information. 7. Regularly monitor network traffic for unusual data exfiltration patterns related to WP EasyCart communications. 8. Maintain up-to-date backups and incident response plans to quickly recover from potential data breaches.
