Detailsinfo

A vulnerability, which was classified as critical, was found in MariaDB Corporation MariaDB Connector Node.js up to 3.2.4/3.3.3/3.4.6/3.5.3. Affected is an unknown code of the component PermitSetMultiParamEntries Handler. The manipulation of the argument key with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-107384 since 10/07/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1505.

Upgrading to version 3.2.5, 3.3.4, 3.4.7 or 3.5.4 eliminates this vulnerability.
