Cross-tenant webhook modification via unscoped route binding
Published Jun 15, 2026 · Updated Jun 15, 2026
Incorrect access control in Deck9 Input 2.0.1 allows remote authenticated users to modify or delete another tenant's webhook. The webhook route parameter is bound independently from the authorized parent form, so update and delete operations act on a webhook without verifying that it belongs to that form. Exploitation requires control of one form and knowledge of another form's webhook identifier; the demonstrated consequence is webhook integrity loss.
