SCA: security update for praisonaiagents (GHSA-qf73-2hrx-xprp)

critical Tenable Self-Hosted Container Security Plugin ID 440048

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 1.5.115, execute_code() in
 praisonaiagents.tools.python_tools defaults to sandbox_mode="sandbox", which runs user code in a
 subprocess wrapped with a restricted __builtins__ dict and an AST-based blocklist. The AST blocklist
 embedded inside the subprocess wrapper (blocked_attrs of python_tools.py) contains only 11 attribute names
 — a strict subset of the 30+ names blocked in the direct-execution path. The four attributes that form a
 frame-traversal chain out of the sandbox are all absent from the subprocess list (__traceback__, tb_frame,
 f_back, and f_builtins). Chaining these attributes through a caught exception exposes the real Python
 builtins dict of the subprocess wrapper frame, from which exec can be retrieved and called under a non-
 blocked variable name — bypassing every remaining security layer. This vulnerability is fixed in 1.5.115.
 (CVE-2026-39888)

Solution

Update the praisonaiagents library and its related packages to version 1.5.115 or later.
