DescriptionCVE.org

A security flaw has been discovered in eosphoros-ai db-gpt 0.7.5. Affected is the function importlib.machinery.SourceFileLoader.exec_module of the file /api/v1/serve/awel/flow/import of the component Flow Import Endpoint. Performing a manipulation as part of File results in code injection. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Remote code injection in eosphoros-ai db-gpt 0.7.5 allows unauthenticated attackers to execute arbitrary code through malicious file uploads to the Flow Import endpoint. The vulnerability exploits unsafe module loading in the file import functionality and has public exploit code available. No patch is currently available from the vendor.
