CVE-2026-57125

Unauthenticated Remote Code Execution via Jobs API and Approval Bypass in PraisonAI Summary An unauthenticated attacker can execute arbitrary OS commands on any server running the PraisonAI Jobs API by submitting a crafted workflow YAML. The attack chains two weaknesses: the /api/v1/runs endpoint requires no credentials, and a top-level approve field in the submitted YAML unconditionally bypasses the @require_approval safety decorator on dangerous tools such as execute_command. Ecosystem: pip | Package: praisonai | Affected: <= 4.6.48 | Patched: *(none)* Details Step 1 — No authentication on the Jobs API POST /api/v1/runs accepts and executes agent jobs from any caller with no token or session required: src/praisonai/praisonai/jobs/router.py:47 @router.post("", response_model=JobSubmitResponse, status_code=202) async def submit_job( request: Request, body: JobSubmitRequest, # accepts agent_yaml from anyone ... missing: _: None = Depends(verify_token) ): Compare with the authenticated endpoint in api/agent_invoke.py, which correctly includes Depends(verify_token). Step 2 — approve YAML field bypasses @require_approval The YAML parser extracts an attacker-controlled approve list and loads it into a ContextVar that the approval decorator consults before every tool call: src/praisonai-agents/praisonaiagents/workflows/yaml_parser.py:261 approve_tools = data.get('approve', []) # attacker-controlled workflow.approve_tools = approve_tools # line 370 src/praisonai-agents/praisonaiagents/workflows/workflows.py:1025 if approve_tools: _approval_token = set_yaml_approved_tools(approve_tools) adds "execute_command" to ContextVar — bypasses decorator src/praisonai-agents/praisonaiagents/approval/init.py:179 if is_yaml_approved(tool_name): # → True mark_approved(tool_name) return func(*args, **kwargs) # executes without prompting Because the bypass is evaluated before any risk-level check, supplying approve: [execute_command] in the submitted YAML is sufficient to
