VulnerabilityCVE-2026-49261cvecve-2026-49261cwe-78
Published: 06/11/2026 (06/11/2026, 17:13:20 UTC)
Source: CVE Database V5
Vendor/Project: MariaDB
Product: server

Description

MariaDB server is a community developed fork of MySQL server. Versions 10.6.1 through 10.6.26, 10.11.1 through 10.11.17, 11.4.1 through 11.4.11, 11.8.1 through 11.8.7, and 12.3.1 with `wsrep_notify_cmd` enabled would execute shell commands embedded in the name of the joiner node. This is fixed in 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2. As a workaround, anyone who cannot upgrade now should disable `wsrep_notify_cmd`.

Technical Analysis

MariaDB server versions 10.6.1 through 10.6.26, 10.11.1 through 10.11.17, 11.4.1 through 11.4.11, 11.8.1 through 11.8.7, and 12.3.1 with wsrep_notify_cmd enabled are vulnerable to OS command injection (CWE-78). This occurs because shell commands embedded in the name of the joiner node are executed, leading to arbitrary code execution. The issue is resolved in MariaDB versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2. The vendor advisory from Red Hat confirms the availability of security updates addressing this vulnerability. The CVSS v3.1 score is 10.0 (critical), reflecting network attack vector, no privileges required, no user interaction, and complete confidentiality, integrity, and availability impact.

Potential Impact

Successful exploitation allows unauthenticated remote attackers to execute arbitrary shell commands on the MariaDB server if wsrep_notify_cmd is enabled, resulting in full system compromise. The vulnerability impacts confidentiality, integrity, and availability of the affected systems.

Mitigation Recommendations

A fix is available in MariaDB versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2. Users should upgrade to these or later versions to remediate the vulnerability. For those unable to upgrade immediately, disabling the wsrep_notify_cmd option will mitigate the risk. Refer to the Red Hat advisories for detailed update instructions.
