CVE-2026-72775

n8n before 1.123.67, 2.31.5, and 2.32.1 contains a SQL injection vulnerability in the PostgresTrigger node, which interpolates user-supplied identifier parameters (channel, function, and trigger names) into SQL statements without proper escaping. An authenticated user can inject arbitrary SQL executed against the connected PostgreSQL database with the configured credential's privileges, allowing full read and write access.

Summary		(es) n8n antes de 1.123.67, 2.31.5 y 2.32.1 contiene una vulnerabilidad de inyección SQL en el nodo PostgresTrigger, que interpola parámetros de identificador proporcionados por el usuario (nombres de canal, función y disparador) en sentencias SQL sin el escape adecuado. Un usuario autenticado puede inyectar SQL arbitrario ejecutado contra la base de datos PostgreSQL conectada con los privilegios de la credencial configurada, permitiendo acceso completo de lectura y escritura.
