• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.6% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2025-11-21 · updated 2026-10-08
• Weakness: CWE-89

Description

The WP Directory Kit plugin for WordPress is vulnerable to SQL Injection via the 'columns_search' parameter of the select_2_ajax() function in all versions up to, and including, 1.4.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
