CVE-2025-7104

A mass assignment vulnerability exists in danny-avila/librechat, affecting all versions. This vulnerability allows attackers to manipulate sensitive fields by automatically binding user-provided data to internal object properties or database fields without proper filtering. As a result, any extra fields in the request body are included in agentData and passed to the database layer, allowing overwriting of any field in the schema, such as author, access_level, isCollaborative, and projectIds. Additionally, the Object.Prototype can be polluted due to the use of Object.assign with spread operators.

Summary		(es) Existe una vulnerabilidad de asignación masiva en danny-avila/librechat, que afecta a todas las versiones. Esta vulnerabilidad permite a los atacantes manipular campos sensibles al vincular automáticamente datos proporcionados por el usuario a propiedades internas de objetos o campos de la base de datos sin un filtrado adecuado. Como resultado, cualquier campo adicional en el cuerpo de la solicitud se incluye en agentData y se pasa a la capa de la base de datos, lo que permite sobrescribir cualquier campo en el esquema, como author, access_level, isCollaborative y projectIds. Además, el Object.Prototype puede ser contaminado debido al uso de Object.assign con operadores de propagación.
