CVE-2026-4516Network attack vector

Authenticated code execution via DataInterpreter injection

Published Mar 21, 2026 · Updated Mar 21, 2026

Code injection in MetaGPT 0.8.0 through 0.8.1 allows remote authenticated users to execute code through DataInterpreter input. The public record identifies metagpt/actions/di/write_analysis_code.py, but does not disclose the input field, parsing step, or execution sink that mishandles untrusted data. Low-privileged access is required, and successful exploitation can read or alter data and interrupt the MetaGPT process.
