CVE-2026-119129：ZITADEL 3.0.0–3.4.15 與 4.0.0–4.19.5 之前版本，透過裝置授權批准實現帳號被盜
CVE-2026-119129 - ZITADEL 3.0.0 through 3.4.15 and 4.0.0 before 4.19.5 Account Takeover via Device Authorization Approval
ZITADEL 3.0.0 以至 3.4.15 以及 4.0.0 之至 4.19.5 之前版本，存在授權漏洞，允許攻擊者在受害者已登入時使用裝置授權批准取得 Token，進而取得帳號存取權。
此漏洞允許攻擊者在受害者已登入時授權 OAuth 2.0 裝置，透過惡意連結取得存取權，並可繞過專案存取設定，提醒使用者及時升級並加強授權設定，以防止帳號被盜，並建議審查 OIDC 設定。
ZITADEL 3.0.0 through 3.4.15 and 4.0.0 before 4.19.5 contains a missing authorization vulnerability in Login V2 that allows attackers to approve OAuth 2.0 device authorizations using a victim's existing session without consent. Attackers can send a signed-in user a link carrying the attacker's user code to obtain the victim's tokens, and can bypass project access settings via the OIDC device authorization API.
