What the vulnerability does

01Description

Nezha from 2.2.5 before 2.3.15 contains an information disclosure vulnerability that allows authenticated users to retrieve third-party credentials because listDDNS omits WebhookURL and WebhookRequestBody redaction. Admins or PATs with nezha:ddns:read scope can call GET /api/v1/ddns to read cleartext tokens embedded in every user's DDNS webhook profiles.
