CVE-2026-59509: cve-search 4.0-6.0.0 - Unauthenticated NoSQL Injection

id: CVE-2026-59509

info:
  name: cve-search 4.0-6.0.0 - Unauthenticated NoSQL Injection
  author: str4k3r
  severity: critical
  description: |
    cve-search versions 4.0 through 6.0.0 expose an unauthenticated DataTables endpoint that accepts attacker-controlled MongoDB collection, projection, filtering, and pagination parameters. This detector uses a harmless invalid projection field against the intended cves collection; version 6.0.1 rejects that field.
  impact: |
    An unauthenticated network attacker can read unintended MongoDB data, including administrative usernames and password hashes when local authentication is enabled, by controlling DataTables query parameters.
  remediation: |
    Upgrade cve-search to v6.0.1 or later.
