CVE-2026-16146: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in matthiasnordwig Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms
The Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms plugin for WordPress is vulnerable to generic SQL Injection via Pattern JSON Keys/Values in all versions up to, and including, 5.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
AI Analysis
Technical Summary
CVE-2026-16146 describes an SQL Injection vulnerability in the Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms WordPress plugin. The flaw arises from improper neutralization of special elements in SQL commands (CWE-89) due to insufficient escaping of user-supplied JSON pattern keys and values. Authenticated attackers with editor or higher privileges can inject additional SQL queries into existing queries, enabling unauthorized data extraction from the database. The vulnerability affects all plugin versions up to and including 5.1. No official fix or patch has been documented as of the publication date.
Potential Impact
An attacker with editor-level or higher access can exploit this vulnerability to perform SQL Injection attacks, allowing them to extract sensitive information from the database. The vulnerability does not impact availability or integrity but compromises confidentiality. There are no known exploits in the wild currently. The medium CVSS score (4.9) reflects the requirement for authenticated access and the limited scope of impact to confidentiality only.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict editor-level access to trusted users only and monitor for suspicious activity. Avoid using affected versions (<=5.1) in sensitive environments if possible.
