CVE-2026-108115
Kortix Suna 0.10.7 before 0.13.52 contains a server-side request forgery vulnerability that allows project managers to bypass the isPrivateIp guard by supplying IPv6 6to4 or Teredo addresses that embed private IPv4 destinations.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
