CVE-2026-29067 Â (opens in a new tab)How to fix?
Upgrade github.com/zitadel/zitadel/internal/api/oidc to version 4.7.1 or higher.
Overview
github.com/zitadel/zitadel/internal/api/oidc is a package for identity infrastructure
Affected versions of this package are vulnerable to Open Redirect via manipulation of the Forwarded or X-Forwarded-Host headers used to construct password reset confirmation links. An attacker can gain unauthorized access to user accounts by tricking users into clicking a malicious password reset link, allowing the attacker to capture the secret reset code and reset the user's password.
Note: This is only exploitable if Multi-Factor Authentication (MFA) or Password-less authentication is not enabled for the targeted account.
Workaround
This vulnerability can be mitigated by configuring a fronting proxy to delete all forwarded header values or set them to the requested host before sending requests to self-hosted environments.
