CVE-2026-56075Public exploitNetwork attack vector

Authenticated command execution via hardcoded auto-approval

Published Jun 18, 2026 · Updated Jun 18, 2026

Command execution in PraisonAI before 4.5.128 allows remote authenticated users to run arbitrary shell commands through the Chainlit UI. The chat.py and code.py modules overwrite ToolConfig.from_env() with approval_mode="auto", then acp_execute_command passes blocklist-approved input to subprocess.run with shell=True. Access to the UI is required; commands run with the PraisonAI process privileges and can read, modify, or delete accessible data or interrupt the host.
