CVE-2026-44168: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in MariaDB server
CVE-2026-44168 is an OS command injection vulnerability in MariaDB server affecting specific versions during the SST (State Snapshot Transfer) process. The donor node interpolates parameters sent by the joiner into the command line without proper validation, allowing a malicious joiner to execute arbitrary shell commands on the donor side via the mariabackup SST method. This vulnerability has been patched in later versions.
AI Analysis
Technical Summary
MariaDB server versions 10.6.1 to before 10.6.26, 10.11.1 to before 10.11.17, 11.4.1 to before 11.4.11, 11.8.1 to before 11.8.7, and exactly 12.3.1 contain an OS command injection vulnerability (CWE-78) during the SST process. The donor node interpolates parameters from the joiner into shell commands without sufficient validation, enabling arbitrary command execution on the donor side via the mariabackup SST method. The issue is fixed in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2.
Potential Impact
Successful exploitation allows a malicious joiner node to execute arbitrary shell commands on the donor node during SST, potentially leading to full compromise of the donor server's confidentiality, integrity, and availability. The CVSS v3.1 score is 8.0 (High), reflecting network attack vector, high privileges required, no user interaction, and complete impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fix is available and has been released in MariaDB server versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2. Users should upgrade to these or later versions to remediate this vulnerability. No vendor advisory content contradicts this; therefore, upgrading is the recommended mitigation.
