The vulnerability in the
run_locally
function stems from trusting LLM-generated content without validation, creating a trust boundary issue (ML09). The original code takes a Dockerfile and files generated by the LLM, writes them directly to disk, and executes Docker commands without any security checks.The patch implements multiple layers of defense:
Input Validation:
Path Traversal Prevention:
Docker Runtime Security:
--security-opt=no-new-privileges=true
flag to prevent privilege escalation--no-cache
for builds to prevent persistent artifactsImproved Error Handling:
This patch ensures that even if the LLM generates malicious content, it will be detected and blocked before execution, significantly reducing the risk of container escapes or privilege escalation attacks.
