CVE-2026-61437Public exploit

Code execution via implicit sibling module import

Published Jul 10, 2026 · Updated Jul 10, 2026

Code injection in PraisonAI before 1.6.78 allows attackers to execute Python code through a crafted workflow and sibling tools.py. AgentFlow._resolve_pydantic_class resolves a string output_pydantic reference by loading and running the workflow directory's tools.py with importlib exec_module, without enforcing the tool-loading opt-in gates. Execution requires a crafted workflow and sibling module to be supplied and then run through WorkflowManager or load_yaml, and the code inherits the runner's privileges.
