CVE-2026-107384
Description
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. From 3.2.0 until 3.2.5, 3.3.4, 3.4.7, and 3.5.4, applications that enable permitSetMultiParamEntries can pass objects whose keys are expanded into a SQL SET clause without being processed by escapeId. An attacker-controlled key containing a backtick can close the quoted identifier and cause the remainder of the key to be interpreted as SQL. This can update columns the application did not intend to expose and can append arbitrary SQL with the database user's privileges. The option is disabled by default, and serialized-object handling used when it is disabled is not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.
