CVE-2026-87074Network attack vector

Unauthenticated email sending via replayable draft token

Published Sep 23, 2026 · Updated Sep 23, 2026

Improper authorization in WPMU DEV Forminator Forms before 1.57.2.1 allows remote attackers to send email containing arbitrary links. The saved-draft notification handler accepts both the recipient address and message link from the request without binding either value to the draft creator. Anonymous visitors receive the send token from the plugin and can replay it without limit, enabling repeated site-branded messages to arbitrary addresses.
