Summary

PraisonAI from 4.5.87 before 4.6.59 does not enforce the dangerous-tool policy check in recipe.run_stream(), a flaw classified as CWE-693. A recipe declaring execute_command is blocked by recipe.run() but reaches the execution engine through recipe.run_stream() with allow_dangerous_tools=False. A local attacker with no privileges needs a user to interact with the recipe, which can lead to high impact on confidentiality, integrity and availability.

Description from the CNA

PraisonAI is a multi-agent teams system. From version 4.5.87 to before version 4.6.59, PraisonAI recipe execution blocks default-denied dangerous tools unless the caller explicitly passes allow_dangerous_tools=True. The normal recipe.run() path enforces this with _check_tool_policy(). The streaming path, recipe.run_stream(), loads the same recipe, checks dependencies, and then calls _execute_recipe() without running the dangerous-tool policy check. As a result, a recipe that honestly declares execute_command in TEMPLATE.yaml requires.tools is denied by recipe.run(), but reaches the execution engine through recipe.run_stream() with allow_dangerous_tools=False. This issue has been patched in version 4.6.59.
