Description
Aureus ERP through 1.6.0 contains an authorization bypass vulnerability that allows authenticated API users to create or move records into disallowed companies by supplying a foreign company_id. Attackers can submit create or update requests to plugin REST API endpoints such as partners, sales, or inventories to break multi-company data segregation.
