Which versions of AIWU Chatbot Plugin are affected by CVE-2026-2993?

The AIWU AI Chatbot WordPress plugin (versions ≤1.4.17) contains an unauthenticated SQL injection vulnerability that allows attackers to extract sensitive database contents without credentials.

How to fix or mitigate CVE-2026-2993?

Within 24 hours: Identify all WordPress instances running AIWU AI Chatbot plugin ≤1.4.17 and disable or remove the plugin immediately as interim containment. Within 7 days: Document affected systems, assess whether nonce protection was enabled in version 1.4.11+, and conduct database access logs review for unauthorized queries. Contact the plugin vendor (Wordfence reference) for patch timeline and consider alternative chatbot solutions. Within 30 days: Once a patched version is confirmed released by the vendor, thoroughly test the update in a staging environment before production deployment, and perform security audit of affected database tables for evidence of compromise.

HIGH 7.5

DescriptionCVE.org

The AI Chatbot & Workflow Automation by AIWU plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 1.4.17 due to insufficient escaping on user supplied parameters and lack of sufficient preparation on the existing SQL query in the getListForTbl() function. 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. NOTE: This issue is partially mitigated by a patch in version 1.4.11 that adds a nonce check for a nonce that is only available to administrators.

AnalysisAI

SQL injection in the AIWU AI Chatbot WordPress plugin (versions ≤1.4.17) allows remote unauthenticated attackers to extract sensitive database contents via the getListForTbl() function due to unsanitized user input in SQL queries. Partial mitigation exists in version 1.4.11+ through administrator-only nonce protection, but the underlying SQL injection vulnerability persists. CVSS 7.5 (High) reflects network-accessible unauthenticated exploitation with high confidentiality impact. Wordfence provides detailed vulnerable code references across multiple plugin files including controller.php, req.php, and model.php. No evidence of active exploitation (not in CISA KEV) at time of analysis.

Technical ContextAI

This is a classic SQL injection vulnerability (CWE-89) in a WordPress plugin's database query layer. The affected product 'AI Chatbot & Workflow Automation by AIWU' (CPE: cpe:2.3:a:wupsales:ai_chatbot_&_workflow_automation_by_aiwu) handles database operations through the getListForTbl() function in its model layer. The vulnerability stems from direct concatenation or interpolation of user-supplied HTTP parameters into SQL queries without proper escaping or use of prepared statements. WordPress provides $wpdb->prepare() for parameterized queries, but the plugin fails to use it consistently. The partial mitigation in 1.4.11 adds a WordPress nonce check that restricts access to certain admin endpoints, but this is authentication bypass prevention rather than input sanitization - the SQL injection payload can still execute if the nonce check is satisfied or bypassed. The references point to specific line numbers in controller.php (L104, L114, L132, L154, L157), req.php (L194), and model.php (L162) showing the vulnerable code patterns across the plugin architecture.

RemediationAI

WordPress site administrators should immediately update the AIWU AI Chatbot plugin to a version beyond 1.4.17 that fully addresses the SQL injection vulnerability, once released by the vendor. As of this analysis, no fully patched version has been confirmed - the vendor's 1.4.11 release only adds nonce authentication, which mitigates but does not eliminate the underlying CWE-89 flaw. Monitor the WordPress plugin repository and Wordfence advisories for a complete security release. Until a proper fix is available, implement these compensating controls: (1) If the chatbot functionality is not business-critical, deactivate and uninstall the plugin entirely - this eliminates all attack surface. (2) If plugin must remain active, restrict wp-admin access to trusted IP addresses via web application firewall rules or .htaccess directives, reducing the attack surface for obtaining administrator nonces. Trade-off: this breaks legitimate remote admin access and may interfere with WordPress mobile apps. (3) Deploy a WordPress security plugin with virtual patching capabilities (e.g., Wordfence, Sucuri) that can filter malicious SQL patterns in HTTP requests. Trade-off: may cause false positives requiring tuning. (4) Enable WordPress database activity logging to detect SQL injection attempts via unusual query patterns. Review the specific vulnerable code locations in controller.php, req.php, and model.php referenced at https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/ to understand your exposure profile.
