ZDI-CAN-28486 HIGH 7.5 Overdue Dec 04, 2025

QNAP

QNAP is a well-known manufacturer of network-attached storage (NAS) devices and storage solutions for both enterprise and consumer markets. This vulnerability has a high CVSS score of 7.5 and requires adjacent network access with high complexity to exploit, but requires no authentication and could result in complete compromise of confidentiality, integrity, and availability once successfully exploited. Security teams should monitor for patches from QNAP (with a vendor deadline of April 3, 2026) and implement network segmentation to restrict access to NAS devices from untrusted adjacent networks in the meantime.
