CVE-2023-3604Public exploitNetwork attack vector

Unauthenticated login URL disclosure via crafted redirect

Published Aug 21, 2023 · Updated Oct 2, 2024

Information exposure in the WPExperts login plugin All In One Login before 1.1.4 allows remote attackers to discover the hidden login URL via crafted URLs. The plugin redirects unauthenticated requests for protected administrative pages to the secret login path, exposing that path instead of concealing it. Any internet-reachable WordPress site using the affected plugin is exposed; the consequence is disclosure of the login endpoint, not direct data modification or service interruption.
