SCA: security update for PraisonAI, praisonaiagents (GHSA-4mr5-g6f9-cfrh)

critical Tenable Cloud Security Plugin ID 442545

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PraisonAI is a multi-agent teams system. Prior to version 4.6.40 of PraisonAI, corresponding to version
 1.6.40 of praisonaiagents, `execute_code()` in `praisonaiagents/tools/python_tools.py` (v1.6.37,
 subprocess sandbox mode) can be fully bypassed using `print.__self__` to retrieve the real Python
 `builtins` module, from which `__import__` can be extracted via `vars()` and runtime string construction.
 This achieves arbitrary OS command execution on the host, completely defeating the sandbox. This is a
 novel bypass that survives all patches for CVE-2026-39888 (frame traversal), CVE-2026-34938 (str
 subclass), and CVE-2026-40158 (`type.__getattribute__` trampoline). PraisonAI version 4.6.40 and
 praisonaiagents version 1.6.40 contain an updated fix. (CVE-2026-47392)

Solution

Update the praisonaiagents library and its related packages to version 1.6.40 or later.
