GHSA-4JCV-VP96-94XR MindsDB Vulnerable to Bypass of SSRF Protection with DNS Rebinding

Summary DNS rebinding is a method of manipulating resolution of domain names to let the initial DNS query hits an address and the second hits another one. For instance the host make-190.119.176.200-rebind-127.0.0.1-rr.1u.ms would be initially resolved to 190.119.176.200 and the next DNS issue to...
