# pgEdge RAG Server: error responses can leak part of a provider API key

Link for people: https://infrastack.ai/live/CVE-2026-125326 (this .md is for agents)

pgEdge RAG Server is an API server for retrieval-augmented generation over PostgreSQL. Before 2.0.0, its unauthenticated query API returns raw error text from failed LLM provider calls, which can quote a partially masked operator API key to any remote caller.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:pgEdge RAG Server affected range not listed fixed no fixed version listed

## How to check

- Check the installed pgEdge RAG Server version; versions before `2.0.0` are affected.
- Look for an unauthenticated query endpoint exposed to the network in the RAG server handlers in `internal/server/handlers.go`.

## Fix

- pgEdge RAG Server: upgrade to `2.0.0`.

## From the sources

pgEdge RAG Server is an API server for retrieval-augmented generation over PostgreSQL content using pgvector. Prior to 2.0.0, the unauthenticated query API in internal/server/handlers.go returns err.Error() from failed LLM provider calls, preserving provider-controlled error text that can quote a partially masked submitted API key. A remote caller can cause an authentication failure and obtain part of the operator's credential for the third-party provider account through the query API error response. This issue is fixed in version 2.0.0.
