cgltf hasta la versión 1.15 contiene una vulnerabilidad de escritura fuera de límites en el heap en cgltf_accessor_unpack_floats() que permite a los atacantes escribir fuera del búfer de salida mediante índices de accesor dispersos (sparse) no comprobados. Los atacantes pueden proporcionar un archivo glTF o GLB manipulado con índices dispersos grandes para corromper la memoria heap, provocar la caída de las aplicaciones y, potencialmente, ejecutar código cuando no se llama a cgltf_validate().
