Horilla is an HR and CRM software. Prior to 2.0.0, HorillaListView.export_data in horilla_views/generic/cbv/views.py accepts an authenticated user's columns POST parameter, takes field_tuple[1], interpolates it into dynamic_fn_str as Python source, and passes the generated function definition to exec(). A crafted string that remains valid under ast.literal_eval can inject Python syntax into a default argument evaluated during function definition, allowing arbitrary operating-system commands to execute with the application process privileges, including root privileges in the shipped Docker image. This issue is fixed in version 2.0.0.
