Vulnerability AssessmentAI

Risk Assessment	The CVSS v3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) indicates network accessibility with low attack complexity and moderate privilege requirements, resulting in a base score of 6.3. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated user of a MetaGPT instance crafts a specially malicious prompt or input containing code injection payloads designed to escape the intended code generation context and inject arbitrary Python commands into the write_analysis_code.py processing pipeline. When the DataInterpreter processes this input without proper sanitization, the injected code is incorporated into generated analysis code and executed on the server with the privileges of the MetaGPT process. …
Remediation	Immediately upgrade Foundation Agents MetaGPT to a version newer than 0.8.1 if available; however, given the lack of vendor response, verify patch availability on the official GitHub repository (https://github.com/geekan/MetaGPT) before upgrading. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 30 days: Identify affected systems running Foundation Agents MetaGPT and apply vendor patches as part of regular patch cycle. …
