CVE-2026-111391
SGLang desde la 0.5.10 hasta la 0.5.22 contiene una vulnerabilidad de inyección de código en _evaluate_filter() que permite a atacantes remotos ejecutar código Python escapando del entorno aislado de eval() (sandbox) mediante re.search __globals__. Los atacantes pueden enviar una expresión de filtro manipulada al endpoint /dumper/configure, sin autenticar, cuando DUMPER_SERVER_PORT está definido, ejecutando código en el proceso del planificador en el siguiente paso hacia delante (forward pass).
