## Technical details

The SaveFormField and UpdateFormRequired API endpoints in ChatWiki before 2.10.0 perform inadequate authorization checks on form_field identifiers. An authenticated attacker can craft requests that combine their own valid form_id with another tenant's sequential form_field ID to bypass ownership validation. The vulnerability requires authentication and allows modification of form field properties, potentially affecting data storage and collection workflows.
