CVE-2026-107383

Description (CNA)

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, the GeoJSON Polygon and MultiPolygon binary encoders size a Buffer.allocUnsafe() allocation from each ring's numeric length before confirming that the ring is an array. A malformed non-array ring can therefore reserve bytes that the writing loop skips, and the connector sends the full buffer through execute() or batch(), disclosing uninitialized Node.js heap data into a database value. The persisted data can include other users' content, session material, database credentials, or TLS key material and may propagate to backups and replicas. The text-protocol query() path is not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.
