Summary

GPUStack through version 2.2.1 contains an unauthenticated information disclosure vulnerability that allows attackers to access sensitive inference logs and modify worker configuration via unprotected /serveLogs and /debug endpoints on the worker port. Attackers can enumerate model instance IDs to stream serving logs containing prompts and completions, change log levels, and read memory profiling data without any authentication.

Risk Assessment

The risk for the organization includes leakage of confidential data processed by AI models (prompts and completions) and the possibility of unauthorized modification of worker configuration, which could lead to system integrity compromise and further attacks.

Recommendation

Immediately update GPUStack to a version containing commit 4e20551 or later, and restrict access to the worker port to trusted networks only.
