Astron Agent is an agentic workflow platform for building and running AI agents. Prior to 1.1.2, the default workflow code-node path through /console-api/workflow/code/run and /workflow/v1/run selects LocalExecutor in core/workflow/engine/nodes/code/code_node.py when CODE_EXEC_TYPE is not explicitly changed. LocalExecutor supplies complete Python builtins to dynamic code execution without the documented sandbox restrictions. An authenticated low-privilege tenant can execute code as root in the core-workflow container and use shared service and database credentials to bypass application-level tenant checks, read or modify other tenants' data, and disrupt shared services. This issue is fixed in version 1.1.2.
