CVE-2026-107385
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
