CVE-2026-15980Known exploitationNetwork attack vector

Unauthenticated account takeover via improper token validation

Published Aug 30, 2026 · Updated Aug 30, 2026

Authentication bypass in TangibleWP MyHome Core 4.4.5 and earlier allows remote attackers to take over unconfirmed accounts. The send_link() AJAX handler lacks authorization, while activate() improperly validates its token and issues a valid authentication cookie for the selected account. Exploitation requires legacy/WPBakery mode, frontend registration and confirmation email, and an account without myhome_agent_confirmed metadata; administrator accounts are exposed when they meet those conditions.
