Published 15 Oct 2026 · NVD status: Awaiting Analysis · AI triage by gemini-3.8-flash

9.4Critical

Attack vector: Network
Complexity: Low
Privileges needed: Low
User interaction: None
Impact: Full C/I/A compromise
Weakness: CWE-61

Impact

Authenticated remote attackers with low-privilege accounts can compromise system security and potentially access or overwrite unauthorized files. They only need valid user credentials on the QNAP device.

Root cause

The application unsafely follows UNIX symbolic links, permitting file access outside intended directory boundaries.

Affected systems

QuMagie versions prior to 2.9.2

CVSS v4.0 · CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X

Fix & remediation

Upgrade QuMagie to version 2.9.2 or later via QNAP App Center. If patching immediately is not possible, disable the QuMagie app or revoke untrusted user account access.

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
