CVE-2026-41497: PraisonAI has an incomplete fix for CVE-2026-34935 - OS Command Injection

April 17, 2026 (updated May 12, 2026)

The fix for PraisonAI’s MCP command handling does not add a command allowlist or argument validation to parse_mcp_command(), allowing arbitrary executables like bash, python, or /bin/sh with inline code execution flags to pass through to subprocess execution.
