CVE-2023-50899Network attack vector

Data exposure and modification via improper capability check

Published Dec 9, 2024 · Updated Apr 28, 2026

Missing authorization in MultiVendorX CatalogX 5.0.2 and earlier allows remote authenticated users to read and modify enquiry data. The catalog_rest_routes_react_module REST endpoints perform an improper capability check, exposing admin-tab data and enquiry-saving operations. Subscriber-level access is the CNA-recorded gate; Wordfence separately reports the REST route as unauthenticated.
