Is this vulnerability remotely exploitable?

It is not directly remotely exploitable in the pure network sense, but remote attackers may exploit it indirectly by getting a malicious `tools.py` into a repository, shared folder, or CI workspace that a user later runs PraisonAI from. Once PraisonAI starts in that directory, the malicious code executes automatically.

What level of access does an attacker need?

An attacker must be able to place or modify a `tools.py` file in the directory where PraisonAI is executed. This can stem from write access to a shared project folder, compromising a Git repository, injecting files through a supply-chain attack, or influencing artifacts that end up in CI/CD workspaces.

What is the safest general fix pattern?

The safest pattern is to remove implicit, name-based auto-loading from the current working directory and replace it with explicit, opt-in plugin registration from a trusted location. Dynamic tools should be loaded only from directories under strict control, with minimal privileges and clear configuration.
