Descriptions
A flaw was found in ansible-runner. An improper escaping of the shell command, while calling the ansible_runner.interface.run_command, can lead to parameters getting executed as host's shell command. A developer could unintentionally write code that gets executed in the host rather than the virtual environment.
Se ha encontrado un fallo en ansible-runner. Un escape inapropiado del comando shell, mientras es llamado a ansible_runner.interface.run_command, puede conllevar a que los parámetros sean ejecutados como el comando shell del host. Un desarrollador podría escribir involuntariamente código que es ejecutado en el host en lugar de en el entorno virtual.
