Description
ChatWiki through 2.9.6 contains an insecure direct object reference vulnerability that allows authenticated users to access another tenant's form filters by supplying arbitrary form_id values. Attackers can send sequential form_id values to getFormFilterList, getFormFilterInfo and updateFormFilterSort to read filter rules and overwrite another tenant's filter sort order.
