How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-58167, inspect your project dependencies for Github.com/ccfos/nightingale/v6:

inspect dependencies for github.com/ccfos/nightingale/v6

Analyze the terminal output to locate any version of Github.com/ccfos/nightingale/v6 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.7.3-0.20260528033214-762819fbaa23), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Github.com/ccfos/nightingale/v6, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
