CVE-2023-51547Network attack vector

Database disclosure via unescaped SQL parameter

Published Dec 31, 2023 · Updated Apr 28, 2026

SQL injection in Fluent Support 1.7.6 and earlier allows remote authenticated users to read database data via crafted input. An insufficiently escaped parameter is concatenated into an existing SQL query, allowing additional statements to be appended. Administrator-level access is required, and the documented consequence is database confidentiality loss with possible query impact.
