How to fix or mitigate EUVD-2026-27188?

Within 24 hours: Identify all WordPress instances running AWP Classifieds plugin and document installed versions. Within 7 days: Either upgrade to version 4.4.6 or later (if available from vendor) or deactivate and remove the plugin; if upgrade is unavailable, implement Web Application Firewall rules to block requests with array syntax in the 'regions' parameter.

DescriptionCVE.org

The AWP Classifieds plugin for WordPress is vulnerable to SQL Injection via the 'regions' parameter array keys in versions up to, and including, 4.4.5 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.

AnalysisAI

SQL injection in AWP Classifieds plugin for WordPress versions up to 4.4.5 allows remote unauthenticated attackers to extract sensitive database contents via array key manipulation in the 'regions' parameter. The vulnerability stems from insufficient escaping of user input in search functionality, affecting the plugin's query integration and page search components. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) and no authentication required, this poses significant risk to WordPress sites running this classifieds plugin, though no public exploit or active exploitation has been identified at time of analysis.

Technical ContextAI

This is a classic SQL injection vulnerability (CWE-89) in WordPress plugin code. The AWP Classifieds plugin (CPE: cpe:2.3:a:strategy11team:awp_classifieds) fails to properly sanitize array keys in the 'regions' parameter before incorporating them into SQL queries. The vulnerable code paths span multiple files including functions.php, page-search-ads.php, class-awpcp.php, and class-query-integration.php as evidenced by the Trac repository references. WordPress plugins must use prepared statements with proper parameterization or WordPress's $wpdb->prepare() method to prevent SQL injection. In this case, the plugin directly concatenates user-supplied array keys into SQL queries without escaping, allowing attackers to inject arbitrary SQL commands. The vulnerability specifically affects the search functionality where regional filters are processed, enabling second-order SQL injection through parameter pollution techniques targeting array key manipulation rather than just values.

RemediationAI

Upgrade AWP Classifieds plugin to version 4.4.6 or later immediately, as the 'up to and including 4.4.5' designation implies a fix exists in subsequent releases. Verify the installed version in WordPress admin under Plugins and update through the WordPress dashboard or manually from the official WordPress plugin repository. If immediate patching is not feasible, implement these compensating controls: disable or restrict access to the plugin's search functionality by removing search shortcodes from public pages or implementing Web Application Firewall (WAF) rules to block requests containing 'regions' parameter with suspicious array key patterns (note: this may break legitimate search functionality for users filtering by region). Deploy database activity monitoring to detect anomalous queries including UNION statements, sleep functions, or information_schema queries originating from the plugin. As a last resort, temporarily deactivate the AWP Classifieds plugin entirely until patching can occur, understanding this will disable all classifieds functionality on the site. Review the Wordfence advisory and WordPress Trac repository links for technical details to inform mitigation decisions.
