PraisonAI flaw lets agents run arbitrary shell commands via forced auto-approval

PraisonAI versions before 4.5.128 hardcoded approval_mode to "auto" in UI modules, overriding the PRAISON_APPROVAL_MODE administrator setting. Authenticated users could instruct the LLM agent to run arbitrary shell commands through subprocess.run with shell=True, bypassing the manual approval gate and command sanitization blocklists.
