CVE-2026-107383

Estado: Pendiente de análisisAlta (7.5)—

MariaDB Connector/Node.js se utiliza para conectar aplicaciones desarrolladas en Node.js a bases de datos MariaDB y MySQL. En versiones anteriores a la 3.2.5, 3.3.4, 3.4.7 y 3.5.4, los codificadores binarios de GeoJSON Polygon y MultiPolygon dimensionan una asignación Buffer.allocUnsafe() a partir de la longitud numérica de cada anillo antes de confirmar que el anillo es un array.

Leer descripción completaMostrar menos

Por tanto, un anillo mal formado que no sea un array puede reservar bytes que el bucle de escritura omite, y el conector envía el búfer completo mediante execute() o batch(), revelando datos no inicializados del heap de Node.js en un valor de la base de datos. Los datos persistidos pueden incluir contenido de otros usuarios, material de sesión, credenciales de base de datos o material de claves TLS y pueden propagarse a copias de seguridad y réplicas. La ruta query() del protocolo de texto no está afectada. Este problema está corregido en las versiones 3.2.5, 3.3.4, 3.4.7 y 3.5.4.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N/UI:N permite explotación remota sin autenticación (T1190). La vulnerabilidad expone datos de heap no inicializados (T1005) incluyendo credenciales y material TLS (T1552).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

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."
