CVE-2025-49916Network attack vectorHinoki check available

Unauthenticated access to ACL-restricted functionality

Published Oct 22, 2025 · Updated Oct 22, 2025

Missing authorization in MultiVendorX 4.2.23 and earlier allows remote attackers to access ACL-restricted functionality. Neither the CNA record nor its sole linked advisory identifies the affected function or the authorization check omitted from it. No authentication or user interaction is required, but the undisclosed action prevents a more specific statement of the data or service consequences.
