ParameterPositionPathDescriptionCWE
baseUrlrequest body/api/provider-nodes/validateThe baseUrl parameter is used to issue server-side HTTP requests. The application fails to properly validate the destination, allowing SSRF to internal resources (e.g., loopback or link-local addresses) because the hostname check is bypassed by IPv4-mapped IPv6 addresses or DNS records pointing to internal IPs.CWE-184, CWE-918
apiKeyrequest body/api/provider-nodes/validateThe apiKey parameter is forwarded to the internal destination as an Authorization Bearer header, which can be used to authenticate against internal services during an SSRF attack.CWE-184, CWE-918
