CVE-2026-44171

MariaDB server is a community developed fork of MySQL server. From 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 12.3.1, mbstream did not check for /../ in the path when unpacking the archive. A proper backup can never contain such paths, but a specially crafted archive could have caused mbstream to create files outside of the target-dir path. This issue has been patched in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2.

Summary		(es) El servidor MariaDB es una bifurcación del servidor MySQL desarrollada por la comunidad. Desde las versiones 10.6.1 hasta antes de la 10.6.26, 10.11.1 hasta antes de la 10.11.17, 11.4.1 hasta antes de la 11.4.11, 11.8.1 hasta antes de la 11.8.7, y 12.3.1, mbstream no verificaba la presencia de /.. / en la ruta al descomprimir el archivo. Una copia de seguridad adecuada nunca puede contener tales rutas, pero un archivo especialmente diseñado podría haber provocado que mbstream creara archivos fuera de la ruta target-dir. Este problema ha sido parcheado en las versiones 10.6.26, 10.11.17, 11.4.11, 11.8.7 y 12.3.2.
