SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the REST v4 JSON handler reads the pre-filter RAW_REQUEST value and relationship write helpers interpolate supplied field values into INSERT and UPDATE statements. The affected flow begins at $GLOBALS['RAW_REQUEST'] and uses set_relationship, SugarRelationship::addRow(), SugarRelationship::updateRow(), and contact_role to carry attacker-controlled data or authorization state into the security-sensitive operation. An authenticated user can inject SQL through relationship fields to read or alter database data and may reach file-write consequences when the database account has elevated privileges. This issue is fixed in versions 7.15.2 and 8.10.2.
