CVE-2026-103253

Estado: AplazadaAlta (7)—

n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain an SQL injection vulnerability in the Oracle Database node's Delete Table Drop operation. Attackers can inject single quotes in the table or schema fields to append arbitrary SQL statements and execute DDL or DML commands against the connected database with the credential's privileges.

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.

SQL injection (CWE-89) en nodo Oracle expuesto permite lectura y manipulación de datos de BD remota sin autenticación previa (AV:N/PR:N).

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.
