CVE-2025-59387Network attack vector

Unauthenticated code execution via undisclosed SQL injection

Published Jan 2, 2026 · Updated Jan 2, 2026

SQL injection in QNAP MARS 1.2.x before 1.2.1.1686 allows remote attackers to execute unauthorized code or commands. QNAP has not disclosed the affected request, parameter, or database query, so the precise locus and unsafe SQL construction operation are not public. No authentication or user interaction is required over the network, and successful exploitation executes attacker-controlled code or commands on the NAS.
