CVE-2026-40287: PraisonAI Vulnerable to RCE via Automatic tools.py Import

April 10, 2026 (updated April 14, 2026)

PraisonAI automatically imports ./tools.py from the current working directory when launching certain components. This includes call.py, tool_resolver.py, and CLI tool-loading paths.

A malicious tools.py placed in the process working directory is executed immediately, allowing arbitrary Python code execution in the host environment.
