CVE-2026-125326: pgEdge RAG Server credential leak in error responses

CVE-2026-125326 · Severity: medium · CVSS 5.8 · Published 2026-11-10

pgEdge RAG Server is an API for retrieval-augmented generation over PostgreSQL databases. The unauthenticated API returns detailed error messages from failed third-party provider calls, which inadvertently leak partial API keys and credentials for those providers. An attacker can trigger an authentication failure and harvest credential fragments through simple API requests.

Technologies: github.com/pgEdge/pgedge-rag-server (Go), pgEdge RAG Server. Vendors: Go, pgEdge.

Technical details

The vulnerability exists in internal/server/handlers.go where unauthenticated query and health endpoints return raw error strings from LLM provider calls via err.Error(). Third-party providers (OpenAI, Anthropic, etc.) echo truncated API keys in their JSON error responses when rejecting credentials; these are preserved and returned to the caller. The health endpoint is particularly easy to exploit—a simple GET /v1/health request with an invalid configured key leaks the credential fragment without any query payload or authentication.
