Vulnerability AssessmentAI

Risk Assessment	High-severity remote code injection in MetaGPT's benchmark evaluation component affecting unauthenticated network access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	Attacker sends crafted input to check_solution function in HumanEvalBenchmark/MBPPBenchmark component, injecting malicious code that executes during solution validation. No authentication required; network-accessible endpoint processes unsanitized manipulation payload directly, enabling remote code execution on MetaGPT instances.
Remediation	Upstream fix available (PR/commit); released patched version not independently confirmed. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify all systems running FoundationAgents MetaGPT versions 0.8.1 and earlier; isolate affected instances from production networks if upgrade cannot be completed immediately. …
