CVE-2026-58167: Nightingale < 9.0.0-beta.2 - Datasource Credential Disclosure to Low-Privilege Users

• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-30 · updated 2026-10-25
• Weakness: CWE-862

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.
