CVE-2022-35277Network attack vector

Administrator API-key update via CSRF

Published Sep 9, 2022 · Updated Apr 28, 2026

Cross-site request forgery in GetResponse Official 5.5.20 and earlier allows remote attackers to alter an administrator's API key via a forged request. The plugin's API-key update handler lacks correct WordPress nonce validation, so a crafted link can submit the change when a logged-in administrator clicks it. The attack requires administrator interaction and can redirect API integration to attacker-controlled credentials, affecting connected-account integrity and confidentiality.
