CVE-2026-48038

joi is a schema description language and data validator for JavaScript. Prior to 17.13.4 and 18.2.1, denial of service is possible via an untrapped exception in services validating user-supplied JSON or object input with recursive link() schemas. When validate() is called without try/catch in a request handler, deeply nested input can trigger an unhandled RangeError and potentially crash the process; lower-impact paths using validateAsync() or try/catch produce a RangeError instead of a structured ValidationError. This issue is fixed in versions 17.13.4 and 18.2.1.

Summary		(es) joi es un lenguaje de descripción de esquemas y un validador de datos para JavaScript. Antes de las versiones 17.13.4 y 18.2.1, es posible la denegación de servicio a través de una excepción no capturada en servicios que validan entradas JSON u objetos proporcionados por el usuario con esquemas link() recursivos. Cuando se llama a validate() sin try/catch en un gestor de solicitudes, una entrada profundamente anidada puede desencadenar un RangeError no manejado y potencialmente bloquear el proceso; las rutas de menor impacto que usan validateAsync() o try/catch producen un RangeError en lugar de un ValidationError estructurado. Este problema está solucionado en las versiones 17.13.4 y 18.2.1.
