CVE-2026-11973 in WP-Lister Lite for eBay Plugin
Summary
by MITRE • 07/29/2026
The WP-Lister Lite for eBay plugin for WordPress is vulnerable to generic SQL Injection via the 'orderby' parameter in all versions up to, and including, 3.8.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WP-Lister Lite for eBay plugin presents a critical security vulnerability classified as generic SQL Injection affecting versions up to and including 3.8.8. This flaw resides in the plugin's handling of the 'orderby' parameter within its database query operations, creating a pathway for unauthorized data extraction through malicious SQL commands. The vulnerability specifically targets authenticated attackers who possess administrator-level privileges or higher, making it particularly concerning given the elevated access requirements necessary to exploit the flaw.
The technical implementation of this vulnerability stems from insufficient input sanitization and improper parameter preparation within the plugin's database interaction code. When the 'orderby' parameter is processed, the system fails to adequately escape user-supplied data before incorporating it into existing SQL queries. This lack of proper input validation creates an environment where attackers can manipulate the query structure by appending additional SQL commands that execute alongside the original database operations. The vulnerability directly maps to CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields, and aligns with ATT&CK technique T1071.004 for application layer protocol manipulation.
The operational impact of this vulnerability extends beyond simple data theft, as authenticated administrators can leverage this weakness to extract sensitive information from the WordPress database through carefully constructed SQL injection payloads. Attackers with administrative access could potentially retrieve user credentials, payment information, plugin configurations, and other confidential data stored within the database. The implications are severe for e-commerce operations relying on WP-Lister Lite for eBay, as the compromised system could lead to financial loss, data breaches, and potential compromise of customer information. The vulnerability's persistence across multiple versions indicates a fundamental flaw in the plugin's security architecture rather than a temporary coding error.
Mitigation strategies should prioritize immediate patching of the affected plugin to version 3.8.9 or later, which addresses the SQL injection vulnerability through proper input sanitization and parameter preparation techniques. Organizations should implement additional defensive measures including regular security audits of WordPress plugins, monitoring for unauthorized administrative access, and maintaining up-to-date backup procedures. Network segmentation and privileged access controls can help limit the potential impact if exploitation occurs, while database query logging and monitoring systems can detect anomalous SQL activity patterns. Security teams should also consider implementing web application firewalls to detect and block common SQL injection attack vectors targeting WordPress installations. The vulnerability serves as a reminder of critical security practices including proper input validation, parameterized queries, and regular security assessments to prevent similar issues in other components of the WordPress ecosystem.
