CVE-2024-50503Network attack vector

Unauthenticated account takeover through user switching

Published Oct 30, 2024 · Updated May 11, 2026

Authentication bypass in Deryck User Toolkit 1.2.3 and earlier allows remote attackers to take over WordPress user accounts. The user-switching path mishandles its browser cookie and inadequately validates a switch request; public sources do not disclose the exact failed check. No authentication or user interaction is required, and successful exploitation grants control of another site account.
