# pgEdge RAG Server: shared BM25 index leaks documents across tenants

Link for people: https://infrastack.ai/live/CVE-2026-125325 (this .md is for agents)

pgEdge RAG Server is an API server that runs retrieval-augmented generation over PostgreSQL content. Before 2.0.0, concurrent unauthenticated queries share one keyword index, so a request can get documents loaded by another request's filter, including another tenant's or customer's data.

_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 below `2.0.0` are affected.
- Check whether the query endpoint is reachable without authentication, and whether one pipeline serves several tenants or customers.
- Server logs cannot show which responses were affected, per the description.

## Fix

- Upgrade pgEdge RAG Server 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 BM25 keyword index is a single per-pipeline object shared by the unauthenticated query endpoint, and concurrent requests lock its clear, refill, and search operations separately. This allows one request to search a corpus populated through another request's search filter, which can return documents belonging to a different tenant or customer without malformed input. The affected responses cannot be identified retrospectively from the server logs. This issue is fixed in version 2.0.0.
