Unauthenticated financial disclosure via missing ownership checks
Published Aug 19, 2026 · Updated Aug 19, 2026
Authorization bypass in YayCommerce YayCurrency before 3.3.5 allows remote attackers to read order and vendor financial data via crafted requests. Its Dokan multi-vendor integration handlers accept user-controlled order or vendor identifiers and return totals, earnings, balance ledgers, and withdrawal histories without capability or ownership validation. No authentication is required, so any internet-reachable store that exposes those handlers leaks confidentiality, with no reported ability to modify data or interrupt service.
