AIWU WordPress Plugin Vulnerable to SQL Injection (CVE-2026-2993)

The AI Chatbot & Workflow Automation by AIWU plugin for WordPress, versions up to and including 1.4.17, contains a SQL Injection vulnerability (CVE-2026-2993). This flaw stems from insufficient input sanitization of user-supplied parameters and inadequate preparation of the SQL query within the getListForTbl() function. Successful exploitation enables unauthenticated attackers to inject malicious SQL queries, potentially extracting sensitive information from the WordPress database. While version 1.4.11 introduced a partial mitigation involving a nonce check, this only affects administrative access and does not fully resolve the vulnerability. This vulnerability allows for database exfiltration and potential compromise of the WordPress site.

Attack Chain

1. An unauthenticated attacker identifies a WordPress site using the vulnerable AI Chatbot & Workflow Automation by AIWU plugin (version <= 1.4.17).
2. The attacker crafts a malicious HTTP request targeting an endpoint that uses the getListForTbl() function.
3. The attacker injects SQL code into a user-supplied parameter within the HTTP request, exploiting the lack of proper sanitization.
4. The injected SQL code is appended to the existing SQL query executed by the getListForTbl() function.
5. The modified SQL query executes against the WordPress database.
6. The attacker leverages the SQL injection to extract sensitive data such as user credentials, API keys, or other confidential information.
7. The extracted data is returned to the attacker via the HTTP response.
8. The attacker may further compromise the WordPress site or connected systems using the exfiltrated data.

Impact

Successful exploitation of this SQL Injection vulnerability (CVE-2026-2993) in the AIWU WordPress plugin can lead to the unauthorized disclosure of sensitive information stored in the WordPress database. This may include user credentials, customer data, API keys, and other confidential information. Depending on the extracted data, attackers could further compromise the WordPress site, escalate privileges, or gain access to connected systems. This poses a significant risk to the confidentiality, integrity, and availability of the affected WordPress site and its data.

Recommendation

• Apply available patches to upgrade the AI Chatbot & Workflow Automation by AIWU plugin for WordPress to a version greater than 1.4.17 to remediate CVE-2026-2993.
• Deploy the Sigma rule “Detect CVE-2026-2993 Exploitation — AIWU WordPress Plugin SQL Injection” to your SIEM to detect exploitation attempts targeting the vulnerable plugin.
