DescriptionCVE.org

pgEdge Go LLM Library provides a unified Go interface for multiple LLM providers with streaming, tool calling, retries, and an HTTP and server-sent events proxy. From 0.1.0 until 0.2.0, GET /v1/health in llm/proxy/handlers.go uses handleHealth to ping providers with the operator's real credentials and returns their error text, while the Authorize hook in llm/proxy/proxy.go permits access by default when the consuming application does not configure it. When a provider rejects the configured credential, a remote caller who can reach the proxy can obtain part of the operator's third-party provider API key from the resulting error. This issue is fixed in version 0.2.0.
