Server-Side Request Forgery (SSRF)

CVE-2025-67494

High
8.6/10

Summary

ZITADEL is an open-source identity infrastructure tool. Versions through 4.7.0 are vulnerable to an unauthenticated, full-read Server-Side Request Forgery (SSRF) vulnerability. The ZITADEL Login UI (V2) treats the "x-zitadel-forward-host" header as a trusted fallback for all deployments, including self-hosted instances. This allows an unauthenticated attacker to force the server to make HTTP requests to arbitrary domains, such as internal addresses, and read the responses, enabling data exfiltration and bypassing network-segmentation controls. This issue is fixed in version 4.7.1.

CWE-918 - Server-Side Request Forgery (SSRF)

Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
