Overview

CVE-2026-58167 is a medium-severity vulnerability. It was published on June 30, 2026 and has a CVSS 3.1 base score of 6.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Nightingale (n9e) before 9.0.0-beta.2 exposes full datasource configurations, including plaintext database passwords, HTTP bearer tokens, HTTP basic-auth passwords, and mTLS client keys, to any authenticated low-privilege (Standard role) user through POST /api/n9e/datasource/list. The route is registered without an admin authorization gate, unlike the sibling datasource mutation routes, and the open-source DatasourceFilter does not redact secret fields, so the secret-bearing settings, http, and auth objects are serialized in the response. The disclosed credentials enable access to the connected downstream systems.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
