Prior to 1.5.115, execute_code() in praisonaiagents.tools.python_tools defaults to sandbox_mode=&#34;sandbox&#34;, 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.</p> <p><strong>Affected:</strong> MervinPraison praisonaiagents</p> <p>PraisonAI is a multi-agent teams system.
