CVE-2026-106056
Rundeck anterior a 6.2.0 contiene una vulnerabilidad de inyección de comandos del sistema operativo que permite a usuarios autenticados con permiso de ejecución de trabajos ejecutar comandos en nodos Windows proporcionando valores de opciones manipulados. Los atacantes pueden inyectar metacaracteres de cmd.exe como && o | en opciones de texto libre, que CLIUtils.quoteWindowsCMDArg envuelve en comillas simples ineficaces, ejecutando comandos con los privilegios de las credenciales del ejecutor del nodo.
