Unauthorized sign-up reassignment via missing ownership check
Published Nov 1, 2024 · Updated Apr 28, 2026
Missing authorization in Fetch Designs Sign-up Sheets 2.2.12 and earlier allows remote attackers to assign sign-ups to other user accounts. The public sign-up submission flow accepts a WordPress user association from a non-logged-in request instead of leaving the record unassociated. No authentication is required, and the bounded impact is unauthorized modification of which WordPress user owns the submitted sign-up record.
