What is CVE-2026-105214?

The Zitadel platform prior to version 4.16.2 is vulnerable to a server-side request forgery (SSRF) issue. This vulnerability allows attackers to bypass security measures by making requests to internal resources through the organization domain's HTTP verification process. Attackers can exploit this flaw by registering domains that redirect to internal addresses, potentially gaining insight into the internal network and its resources. The misuse of Go's default http.Get instead of using a secure client exposes the system to significant risks, enabling attackers to probe internal services and gather sensitive information.
