Description

ZITADEL is an open source identity management platform. From version 4.0.0-rc.1 to 4.7.0, a potential vulnerability exists in ZITADEL's password reset mechanism in login V2. ZITADEL utilizes the Forwarded or X-Forwarded-Host header from incoming requests to construct the URL for the password reset confirmation link. This link, containing a secret code, is then emailed to the user. This issue has been patched in version 4.7.1.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/zitadel/zitadel. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/zitadel/zitadel to 1.80.0-v2.20.0.20251208091519-4c879b47334e or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-29067 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether CVE-2026-29067 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to CVE-2026-29067. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
