CVE-2026-109444
OpenSRE hasta la versión 0.1.2026.10.19 contiene una vulnerabilidad de bypass de la puerta de aprobación que permite a los atacantes ejecutar comandos shell_run sin confirmación, ya que el método execution_allowed() del presentador headless siempre devuelve True. Los atacantes pueden inyectar instrucciones en alertas o mensajes de Slack procesados por el agente para ejecutar comandos en el host y exfiltrar credenciales de LLM, Slack y de la nube.
