CVE-2026-6110Public exploitNetwork attack vector

Remote code execution via unvalidated LLM eval

Published Apr 12, 2026 · Updated Apr 12, 2026

Code injection in MetaGPT 0.8.0 and 0.8.1 allows remote attackers to execute arbitrary Python code through crafted Tree-of-Thought input. The generate_thoughts function in metagpt/strategy/tot.py extracts a code block from the model response and passes it directly to eval without validation. Exploitation requires attacker-controlled input to influence the configured model's response; successful code runs with the MetaGPT process's privileges.
