• CVE-2026-125326: 0.41% estimated exploitation activity in the next 30 days; percentile 35.90 (FIRST EPSS, 2026-11-14). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact An unauthenticated remote caller could read part of the operator's configured LLM provider API key. The query API relayed the text of a provider error straight to the caller. That text carried the upstream provider's own message, and providers characteristically quote a partially masked form of the credential they rejected when authentication fails — so a failing provider call published a fragment of the operator's key. A caller who can reach the endpoint can cause such a failure and read the result. Who is affected: any deployment of pgEdge RAG Server at `1.0.0` or earlier, including all alpha and beta pre-releases, whose query endpoint was reachable by an untrusted party. The endpoint carries no authentication in the affected versions. The disclosed material authenticates to a third-party provider account rather than to pgEdge software, which is why the severity carries Scope: Changed. `v1.0.0:internal/server/handlers.go:121` relayed `err.Error()` to the client…

# Patch Next advisory brief: CVE-2026-125326

Advisory: pgEdge RAG Server discloses part of the configured provider credential through API error messages
IDs: CVE-2026-125326, GHSA-68g8-gh8f-7rhg
Record: https://patchnext.com/advisories/cve-2026-125326 (revision 2, source checked 13 Nov 2026, 06:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/pgEdge/pgedge-rag-server 1.0.1-0.20260729022402-72e0785a6d7c. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/pgEdge/pgedge-rag-server: affected < 1.0.1-0.20260729022402-72e0785a6d7c; fixed in 1.0.1-0.20260729022402-72e0785a6d7c

## Suggested inspection (read-only)
- Go github.com/pgEdge/pgedge-rag-server: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/pgEdge/pgedge-rag-server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
