CVE-2026-29067 is a vulnerability in ZITADEL, an open source identity management platform, affecting versions from 4.0.0-rc.1 to 4.7.0. The issue resides in the login V2 password reset mechanism, where ZITADEL relies on the Forwarded or X-Forwarded-Host header from incoming requests to construct the URL for the password reset confirmation link. This link, which includes a secret code, is then emailed to the user for verification. The flaw corresponds to CWE-601, involving open redirects via untrusted headers.

An attacker with network access can exploit this vulnerability without authentication by sending a crafted request to the password reset endpoint, manipulating the Forwarded or X-Forwarded-Host header to redirect the confirmation link to a malicious domain under their control. This requires user interaction, as the victim must click the phishing-like link in the email (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N). Successful exploitation allows the attacker to capture the secret code, enabling unauthorized password resets and potential account takeover with high confidentiality and integrity impacts.

The vulnerability has been addressed in ZITADEL version 4.7.1. For full details on the patch and mitigation recommendations, refer to the GitHub security advisory at https://github.com/zitadel/zitadel/security/advisories/GHSA-pfrf-9r5f-73f5.

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly checks and rejects untrusted redirect targets before they are used in a response.

Information flow enforcement can restrict redirects to only approved/trusted destinations, stopping untrusted user-supplied URLs from being followed.
