WordPress · Wp-Lister Lite For Ebay · CVE-2026-11973
**Name of the Vulnerable Software and Affected Versions**
WP-Lister Lite for eBay versions prior to 3.8.9
**Description**
The WP-Lister Lite for eBay plugin for WordPress contains a generic SQL Injection flaw. This occurs because the software fails to properly escape user-supplied input and lacks sufficient preparation of the SQL query. Authenticated attackers with administrator-level access or higher can exploit this by appending malicious SQL queries to existing ones via the `orderby` parameter to extract sensitive information from the database.
**Recommendations**
Update WP-Lister Lite for eBay to version 3.8.9 or later.
As a temporary mitigation, restrict access to the `orderby` parameter for administrative users until the update is applied.
