CVE-2026-73617

Budibase before 3.40.0 contains a NoSQL injection vulnerability in the MongoDB datasource integration where user-supplied parameters are enriched with handlebars using noEscaping: true and parsed without operator filtering. Attackers can inject MongoDB operators through query parameters to bypass per-user access controls, read arbitrary documents, execute JavaScript via $where operators, or modify collections through update and delete operations.

Summary		(es) Budibase anterior a la versión 3.40.0 contiene una vulnerabilidad de inyección NoSQL en la integración de fuente de datos de MongoDB donde los parámetros proporcionados por el usuario se enriquecen con handlebars usando noEscaping: true y se analizan sin filtrado de operadores. Los atacantes pueden inyectar operadores de MongoDB a través de parámetros de consulta para eludir los controles de acceso por usuario, leer documentos arbitrarios, ejecutar JavaScript a través de operadores $where o modificar colecciones a través de operaciones de actualización y eliminación.
