Doc Text:
A flaw was found in Meteroid. An authenticated user with coupon management permissions can view, alter, or disable coupons belonging to other tenants by submitting another tenant's coupon identifier. This issue occurs because the coupon status update service does not properly validate tenant ownership, resulting in a cross-tenant authorization bypass and unauthorized data disclosure.

Description OSIDB Bzimport 2026-11-10 19:54:07 UTC
Meteroid 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.
