CVE-2026-107385: MariaDB-Corporation MariaDB-Connector-Node.js

High severity, CVSS 7.4. EPSS: 0.4% chance of exploitation in the next 30 days.

MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.5, 3.3.4, 3.4.7, and 3.5.4, text-protocol escaping always prefixes quotes with a backslash and does not honor the session's NO_BACKSLASH_ESCAPES mode, including in Connection.escape(). When that mode is enabled, the backslash is an ordinary character, so an attacker-controlled placeholder value can close the SQL string literal and inject arbitrary SQL with the application's database privileges. The vulnerable configuration may be enabled server-wide, through connector initialization options, or with an application-issued SET sql_mode; execute() and batch() use binary protocols and are not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.

Affected products

• MariaDB-Corporation MariaDB-Connector-Node.js: before 3.2.5 (fixed in 3.2.5); from 3.3.0, before 3.3.4 (fixed in 3.3.4); from 3.4.0, before 3.4.7 (fixed in 3.4.7); from 3.5.0-rc.0, before 3.5.4 (fixed in 3.5.4)
