Summary

pgEdge RAG Server, an API server for retrieval-augmented generation over PostgreSQL content, has a flaw in its shared keyword index that lets an unauthenticated attacker remotely, without logging in, retrieve documents belonging to other tenants or customers, and the bug occurs under concurrent requests with no malformed input needed. Because the bug requires a specific timing condition, it is harder to trigger, and affected responses cannot be identified from server logs.

Read the original description

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.

Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-125325 (pgEdge RAG Server shared keyword index leaked results between concurrent unauthenticated requests), 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-2026-125325 (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-2026-125325 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-125325 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/security/advisories/GHSA-w437-9mwm-j6vq
- https://github.com/pgEdge/pgedge-rag-server/pull/44
- https://github.com/pgEdge/pgedge-rag-server/commit/a09d4872356b510c81f11591845445c33ff45a84
- 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.
