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)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
