CVE-2024-31673Public exploitNetwork attack vector

Database disclosure via unescaped userid query

Published May 3, 2024 · Updated Aug 5, 2024

SQL injection in load_data.php in Kliqqi CMS 2.0.2 allows remote attackers to read database data through the userid parameter. The endpoint copies userid from the request into link_author and other numeric SQL predicates without escaping or parameterization. No authentication is required; crafted POST requests can use response differences as a Boolean oracle to extract database values.
