Summary
mariadb vulnerabilities
Details

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 intended target directory. (CVE-2026-44171)

It was discovered that MariaDB's mysqlrealescape_string() function incorrectly handled the big5 character set. An attacker could possibly use this issue to perform SQL injection attacks. (CVE-2026-44172)

It was discovered that MariaDB did not properly check the FILE privilege when the FROM clause of a SELECT ... INTO OUTFILE or SELECT ... INTO DUMPFILE statement contained only subqueries. An authenticated user could possibly use this issue to write files to unintended locations. (CVE-2026-44173)

It was discovered that MariaDB did not properly validate parameters supplied by a joiner node during a State Snapshot Transfer using the rsync method. An attacker could possibly use this issue to execute arbitrary shell commands on the donor node. (CVE-2026-48163)

It was discovered that MariaDB allowed a high-privileged user to set certain Galera system variables to values containing shell commands, which were then executed by the server process. An authenticated user could possibly use this issue to execute arbitrary shell commands. (CVE-2026-48165)

It was discovered that MariaDB executed shell commands embedded in the name of a joiner node when wsrepnotifycmd was enabled. A remote attacker could possibly use this issue to execute arbitrary shell commands. (CVE-2026-49261)
