Detailsinfo

A vulnerability was found in MariaDB Server up to 10.6.25/10.11.16/11.4.10/11.8.6/12.3.1. It has been classified as problematic. Affected is some unknown processing of the component Archive Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-44171 since 05/05/2026. The exploitability is told to be difficult. Local access is required to approach this attack. Additional levels of successful authentication are necessary for exploitation. The technical details are unknown and an exploit is not available.
