CRITICAL 9.8REMOTEUPGRADE

CVE-2026-41497 is a critical-severity flaw (CVSS 9.8) affecting praisonai. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

PraisonAI is a multi-agent teams system. Prior to version 4.6.9, 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. This issue has been patched in version 4.6.9.
