CVE-2021-22701Network attack vector

Unintended device actions via forged web requests

Published Feb 19, 2021 · Updated May 29, 2026

Cross-site request forgery in Schneider Electric PowerLogic meter web interfaces allows attackers to trigger unintended device actions. Schneider Electric identifies the affected locus as the HTTP web interface but does not disclose the request handler or missing anti-forgery validation. A highly privileged user must interact with attacker-controlled content while authenticated, and public records do not identify the exact resulting action.
