CVE-2026-107822

SQL injection vulnerability in MariaDB (versions 3.3.18 and 3.4.8) despite using mysql_real_escape_string() with big5 charset. Fixed in versions 3.3.19 and 3.4.9.

A vulnerability in MariaDB on Windows with the CONNECT engine installed and REST support enabled allows interpolation of the table HTTP attribute into the curl command line without proper sanitization. This enables the user to execute shell commands on the server.

MariaDB from 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the view FRM parser did not safely encode embedded newline characters in a username. An account with CREATE USER and CREATE VIEW WITH GRANT OPTION could create a crafted username containing additional view metadata, potentially escalating database privileges.

MariaDB from 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, insufficiently validated counts, offsets, lengths, and field boundaries in FRM metadata while opening binary FRM files. An attacker able to place a crafted FRM file in the data directory could trigger out-of-bounds reads or writes, crash the server, or potentially execute code.

MariaDB from 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the mariadb.service unit used /run/mysqld/wsrep-new-cluster during the next service restart. A database user with FILE privilege and a secure-file-priv configuration permitting writes to /run/mysqld could create that file and inject attacker-controlled environment values into the restarted service.

A vulnerability in MariaDB server allows a high-privileged user to execute shell commands via the wsrep_sst_receive_address or wsrep_sst_donor global system variables. Affected versions range from 10.6.1 to before 10.6.27, 10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1.

A vulnerability in MariaDB allows a malicious joiner node to execute arbitrary shell commands on the donor node during the SST (State Snapshot Transfer) process using the rsync method. The issue stems from insufficient validation of parameters sent by the joiner, which are interpolated into the command line on the donor side.

A vulnerability in MariaDB allows SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE without the required FILE privilege when the FROM clause contains only subqueries. Affected versions include 10.6.1 to 10.6.26, 10.11.1 to 10.11.17, 11.4.1 to 11.4.11, 11.8.1 to 11.8.7, and 12.3.1.

A vulnerability in MariaDB allows a malicious joiner node to execute arbitrary shell commands on the donor node during the SST (Snapshot State Transfer) process using the mariabackup method. The issue is caused by insufficient validation of parameters sent by the joiner, which are interpolated into the command line on the donor side.

In MariaDB server up to version 11.8.5, when the server audit plugin is enabled with the server_audit_events variable configured with QUERY_DCL, QUERY_DDL, or QUERY_DML filtering, an authenticated database user can invoke a SQL statement prefixed with double-hyphen (--) or hash (#) style comments, which is not logged.
