CVE-2026-55522Public exploit

Arbitrary code execution via ungated recipe tool import

Published Aug 5, 2026 · Updated Aug 5, 2026

Code injection in PraisonAI 3.9.26 through 4.6.57 and praisonaiagents 0.12.12 through 1.6.57 lets attackers run code via a recipe. Workflow._execute_include() passes an included tools.py path to importlib.util.spec_from_file_location() and exec_module() without enforcing either autoload opt-in gate. Execution occurs as the PraisonAI process user before workflow parsing or a model call, after a victim process is induced to include an attacker-controlled local recipe.
