CVE-2026-44172: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in MariaDB server
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.
AI Analysis
Technical Summary
MariaDB server versions 3.3.18 and 3.4.8 contain an SQL injection vulnerability due to improper handling of the big5 character set when escaping user input with mysql_real_escape_string() over the text protocol. This function was expected to prevent SQL injection but failed under these conditions. The vulnerability is identified as CWE-89 and has a CVSS 4.0 base score of 6.9 (medium severity). Red Hat's advisory confirms the issue and provides updated mariadb-connector-c packages that fix the vulnerability. The fix is included in MariaDB server versions 3.3.19 and 3.4.9 and corresponding Red Hat Enterprise Linux updates.
Potential Impact
The vulnerability allows attackers to perform SQL injection attacks despite the use of mysql_real_escape_string(), potentially leading to unauthorized database queries or data manipulation. The impact is limited to applications using the big5 character set with the vulnerable MariaDB versions. No known exploits in the wild have been reported as of the advisory date.
Mitigation Recommendations
A fix is available and has been released in MariaDB server versions 3.3.19 and 3.4.9. Red Hat has issued updated mariadb-connector-c packages for Red Hat Enterprise Linux 10.0 Extended Update Support that address this vulnerability. Users should apply these official updates promptly to remediate the issue. Patch status is confirmed by the vendor advisory. No additional mitigation steps are indicated beyond applying the official patches.
