AI-suggested

A fix is available in PraisonAI version 4.6.37 and praisonaiagents version 1.6.37. Users should upgrade to these versions or later to remediate this vulnerability. Patch status is not explicitly stated beyond the version fix; therefore, verify with the vendor advisory for the latest remediation guidance.

Description

PraisonAI is a multi-agent teams system. Prior to praisonai version 4.6.37 and praisonaiagents version 1.6.37, praisonaiagents resolves unresolved tool names against module globals and __main__ after it fails to match the declared tool list and the registry. With the default agent configuration, _perm_allow is None, so undeclared non-dangerous tool names are not rejected by the permission gate. An attacker who can influence tool-call names can therefore invoke unintended application callables that were never declared as tools. This issue has been patched in praisonai version 4.6.37 and praisonaiagents version 1.6.37.
