GHSA-r3rv-jm3r-62q2: mariadb (CVE-2026-107385)

Package	Ecosystem	Affected	Fixed in
mariadb	npm	<3.2.5 \|\| >=3.3.0, <3.3.4 \|\| >=3.4.0, <3.4.7 \|\| >=3.5.0-rc.0, <3.5.4	3.2.5, 3.3.4, 3.4.7, 3.5.4

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of the npm package mariadb below 3.2.5, from 3.3.0 to below 3.3.4, from 3.4.0 to below 3.4.7, and from 3.5.0-rc.0 to below 3.5.4 have an SQL injection flaw in text-protocol parameter escaping. When the session runs with NO_BACKSLASH_ESCAPES enabled, the connector escapes quotes with a backslash, so a value passed as a query parameter can break out of its string literal and run as SQL with the application database user's privileges. Upgrade to 3.2.5, 3.3.4, 3.4.7, 3.5.4 or later. Until then, use execute() or batch(), which are not affected, or do not enable NO_BACKSLASH_ESCAPES.
