NocoBase: SSRF in customRequests:send via runtime options.url override

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Versions 2.1.0 through 2.1.14 contain a server-side request forgery vulnerability in the customRequests:send endpoint. A low-privileged authenticated user can override the stored request URL at runtime using options.url, causing the NocoBase server to send requests to attacker-controlled or internal destinations. Exploitation could expose internal services, Docker host gateways, or cloud metadata endpoints and allow the server to be used as a trusted network proxy. This issue has been fixed in version 2.1.15.
