GHSA-ffp3-3562-8cv3: PraisonAI: Coarse-Grained Tool Approval Cache Bypasses Per-Invocation Consent for Shell Commands

The approval system in PraisonAI Agents caches tool approval decisions by tool name only, not by invocation arguments. Once a user approves execute_command for any command (e.g., ls -la), all subsequent execute_command calls in that execution context bypass the approval prompt entirely. Combined with os.environ.copy() passing all process environment variables to subprocesses, this allows an LLM agent (potentially via prompt injection) to silently exfiltrate API keys and credentials without further user consent.
