DescriptionMeteroid before 2.2.0 contains a cross-tenant authorization bypass vulnerability in the CouponsService UpdateCouponStatus gRPC handler, whose UPDATE query filters only on coupon id and ignores tenant ID. Authenticated users with catalog:manage or a tenant-scoped API key can supply another tenant's coupon ID to disable, archive, or re-enable that coupon and receive its details.
