DescriptionCVE.org

A vulnerability was detected in FoundationAgents MetaGPT up to 0.8.1. This affects the function check_solution of the component HumanEvalBenchmark/MBPPBenchmark. Performing a manipulation results in code injection. The attack may be initiated remotely. The exploit is now public and may be used. The project was informed of the problem early through a pull request but has not reacted yet.

AnalysisAI

Code injection in FoundationAgents MetaGPT versions up to 0.8.1 allows unauthenticated remote attackers to execute arbitrary code through the check_solution function in HumanEvalBenchmark and MBPPBenchmark components. The vulnerability requires no user interaction and enables unauthorized access, data modification, and service disruption. Publicly available exploit code exists, disclosed via GitHub issue #1942. Vendor has not responded to early disclosure via pull request #1988 at time of analysis.

Technical ContextAI

CWE-94 code injection flaw in check_solution function within benchmark evaluation modules. Unsanitized input to code execution context permits arbitrary code injection. CVSS vector AV:N/AC:L/PR:N confirms network-accessible attack with low complexity and no authentication requirement. Affects FoundationAgents MetaGPT cpe:2.3:a:foundationagents:metagpt:*:*:*:*:*:*:*:* through version 0.8.1.

RemediationAI

Upstream fix available (PR/commit); released patched version not independently confirmed. Vendor notified via GitHub pull request #1988 (https://github.com/FoundationAgents/MetaGPT/pull/1988) but has not issued formal response or release at time of analysis. Organizations should monitor vendor repository for patched release incorporating PR #1988 fix. Until patched version available, implement strict input validation on all user-supplied data passed to HumanEvalBenchmark and MBPPBenchmark check_solution functions. Consider disabling affected benchmark components if not operationally required. Apply network segmentation to limit remote access to MetaGPT instances. Review VulDB advisory https://vuldb.com/vuln/356524 and GitHub issue #1942 for additional technical details and potential workarounds.
