SQL injection in MariaDB Connector/C - CVE-2026-44172

Vulnerability identifier: #VU131788

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-44172

CWE-ID: CWE-89

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform SQL injection.

The vulnerability exists due to improper neutralization of special elements used in an SQL command in mysql_real_escape_string() when escaping non-validated user input for queries sent using the text protocol with the big5 character set. A remote attacker can supply crafted input to perform SQL injection.

The issue occurs in applications that interpolate escaped parameters into query strings instead of using a safer query construction method.
