CVE-2026-16094

Name of the Vulnerable Software and Affected Versions Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms versions prior to 5.2

Description This issue is a generic SQL Injection, which occurs when an application fails to properly sanitize user input, allowing an attacker to interfere with the queries that an application makes to its database. Authenticated attackers with editor-level access and above can append additional SQL queries to existing ones to extract sensitive information from the database. This is caused by insufficient escaping of the user-supplied key parameter and a lack of sufficient preparation on the existing SQL query.

Recommendations Update to a version newer than 5.1. Avoid using the key parameter until the software is updated.
