PraisonAI is a multi-agent teams system. Versions 4.5.138 and below are vulnerable to arbitrary code execution through automatic, unsanitized import of a tools.py file from the current working directory. Components including call.py (import_tools_from_file()), tool_resolver.py (_load_local_tools()), and CLI tool-loading paths blindly import ./tools.py at startup without any validation, sandboxing, or user confirmation. An attacker who can place a malicious tools.py in the directory where PraisonAI is launched (such as through a shared project, cloned repository, or writable workspace) achieves immediate arbitrary Python code execution in the host environment. This compromises the full PraisonAI process, the host system, and any connected data or credentials. This issue has been fixed in version 4.5.139.
AnalysisAI
Arbitrary Python code execution in PraisonAI ≤4.5.138 occurs when malicious tools.py files are automatically imported from the current working directory without validation. Attackers placing a crafted tools.py in shared projects, cloned repositories, or writable workspaces achieve immediate code execution with full process privileges upon PraisonAI startup. …

RemediationAI
Within 24 hours: Identify all systems running PraisonAI ≤4.5.138 and isolate high-risk instances (those processing sensitive data or operating in shared environments). Within 7 days: Implement network-level controls restricting PraisonAI process execution and enforce code review policies for all tools.py files before repository cloning or workspace setup. …
