CVE-2023-52147Network attack vector

Hidden login-page disclosure via URL encoding

Published Jun 4, 2024 · Updated Apr 28, 2026

Information disclosure in TeamUpdraft All-In-One Security 5.2.4 and earlier allows remote attackers to discover hidden login URLs. On WordPress multisite installations, the renamed-login route mishandles URL-encoded requests and reveals the concealed login-page location. Exploitation requires multisite mode and the rename-and-hide login feature; disclosure only defeats login-page concealment and does not grant authentication.
