Title

MariaDB: mysql_real_escape_string() incorrectly handled big5

Summary

MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to the database using text protocol and big5 character set was vulnerable to SQL injections, even though mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19 and 3.4.9.

CVE-2026-44172

A flaw was found in MariaDB server. An application processing non-validated user input, which then uses `mysql_real_escape_string()` and sends data to the database via text protocol with the big5 character set, is vulnerable to SQL injection. This allows a remote attacker to execute malicious SQL commands, potentially leading to unauthorized data access or modification within the database.

9.1 (Critical)
