Arbitrary Command Injection Affecting composio-core package, versions [,0.6.9)

composio-core is a Core package to act as a bridge between composio platform and other services.

Affected versions of this package are vulnerable to Arbitrary Command Injection via the handle_tool_calls function due to improper user input sanitization.
