ChatWiki before 2.10.0 contains an insecure direct object reference vulnerability in SaveFormField and UpdateFormRequired that allows authenticated users to modify other tenants' form fields. Attackers can pass their own form_id to satisfy the ownership check alongside another tenant's sequential form_field id to alter field names, descriptions, types and required flags, disrupting how submitted entries are stored.
