What is CVE-2026-39307?

PraisonAI is a multi-agent teams system that has a vulnerability in its templates installation feature prior to version 1.5.113. The application utilizes Python's zipfile.extractall() method to download and extract template archives from external sources, such as GitHub. However, it fails to verify whether the contents of the archive could resolve outside the intended extraction directory, exposing users to potential arbitrary file write attacks. This vulnerability has been patched in version 1.5.113, highlighting the importance of secure file handling and validation mechanisms in software development.
