Summary

mariadb security update

Details

MariaDB is a community developed fork from MySQL - a multi-user, multi-threaded SQL database server. It is a client/server implementation consisting of a server daemon (mariadbd) and many different client programs and libraries. The base package contains the standard MariaDB/MySQL client programs and utilities.

Security Fix(es):

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.(CVE-2026-49261)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
