CVE-2024-37444Network attack vector

Unauthenticated service interruption via Configs authorization gap

Published Nov 1, 2024 · Updated Apr 28, 2026

Missing authorization on the Configs page in WPMU DEV Defender Security 4.7.1 and earlier allows remote attackers to interrupt service. The Configs page fails to enforce an authorization check before processing an otherwise privileged action; public sources do not identify the handler or action. No account or user interaction is required, and the published impact is limited to service interruption without reported data access or modification.
