What is CVE-2026-47398?

A vulnerability exists within PraisonAI versions prior to 4.6.40 due to unguarded exec_module call sites in agents_generator.py. These functions execute modules specified in YAML configurations without proper validation, leaving the software exposed to potential remote code execution attacks. To mitigate the risks, it is crucial for organizations to upgrade to version 4.6.40 or later where this issue has been addressed.

Affected Version(s)
