Forminator Forms - Security Vulnerability (CVE-2026-87074)

CVE-2026-87074

The Forminator Forms WordPress plugin before 1.57.2.1 does not bind its saved-draft notification to the visitor who created the draft, and takes both the recipient address and the link written into the message from the request, so unauthenticated visitors can make the site send a message from its own mail configuration to any address, carrying a link of their choosing inside the site's own template. The token that authorises the send is handed to the anonymous caller by the Forminator Forms WordPress plugin before 1.57.2.1 itself and can be replayed without limit.
