ThinkDashboard: Blind Server-Side Request Forgery (SSRF) vulnerability in /api/ping Endpoint

ThinkDashboard is a self-hosted bookmark dashboard built with Go and vanilla JavaScript. Versions 0.6.7 and below contain a Blind Server-Side Request Forgery (SSRF) vulnerability, in its `/api/ping?url= endpoint`. This allows an attacker to make arbitrary requests to internal or external hosts. This can include discovering ports open on the local machine, hosts on the local network, and ports open on the hosts on the internal network. This issue is fixed in version 0.6.8.
