Summary
The Fluent Forms WordPress plugin before 6.2.5 does not properly restrict the deletion of form submission entries to the forms a restricted Manager is authorized to manage, allowing a Manager limited to specific forms to permanently delete submission entries belonging to other forms. This requires a non-default configuration in which an administrator has created at least one Manager restricted to specific forms.
