CVE-2026-49261 [HIGH] MariaDB vulnerabilities
Title: MariaDB vulnerabilities
Summary: Several security issues were fixed in MariaDB.
It was discovered that MariaDB did not properly validate parameters
supplied by a joiner node during a State Snapshot Transfer using the
mariabackup method. An attacker could possibly use this issue to execute
arbitrary shell commands on the donor node. (CVE-2026-44168)
It was discovered that MariaDB did not properly enforce the SHOW CREATE
ROUTINE privilege when a user obtained access to a stored routine via a
role. An authenticated user could possibly use this issue to obtain
sensitive information. (CVE-2026-44169)
It was discovered that MariaDB's mbstream utility did not properly validate
paths when unpacking archives. An attacker could possibly use this issue to
write files outside of the intende
