Summary

Kortix Suna from 0.10.7 before 0.13.52 contains a server-side request forgery flaw (CWE-918) in its private IP check. The isPrivateIp guard fails to block IPv6 6to4 and Teredo addresses that embed private IPv4 destinations, so the check can be bypassed. An attacker holding the project.connector.write permission can point connector URLs at internal services and cloud metadata endpoints and read the responses. A public exploit is linked in the references.
