What is CVE-2026-111387?

The Nezha Management System version 2.2.5 and prior contains a vulnerability that permits authenticated users to access sensitive third-party credentials. This occurs because the listDDNS operation fails to properly redact certain elements, such as WebhookURL and WebhookRequestBody, allowing users with the appropriate permissions (nezha:ddns:read scope) to retrieve cleartext tokens from each user's DDNS webhook profiles through the GET /api/v1/ddns endpoint.

Affected Version(s)

nezha 2.2.5 < 2.3.15
