## Summary

pgEdge RAG Server, an API server for retrieval-augmented generation over PostgreSQL content, can leak part of the operator's third-party LLM provider API key through its unauthenticated query API error messages. A remote attacker without logging in can trigger an authentication failure and read the partially masked key from the returned error text.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- pgEdge pgedge-rag-server: fixed in 2.0.0

## Description

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.

## What to do

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-125326 (pgEdge RAG Server discloses part of the configured provider credential through API error messagespgEdge RAG Server discloses part of the…), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-125326 (entry last updated 2026-11-10):
Affected:
- pgEdge pgedge-rag-server: fixed in 2.0.0
Fixed versions: 2.0.0.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-125326 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-125326 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

- https://github.com/pgEdge/pgedge-rag-server/releases/tag/v2.0.0
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
