Authenticated command injection in QNAP QTS and QuTS hero NAS operating systems allows an attacker who already holds an administrator account to execute arbitrary OS commands on the appliance. The flaw carries a CVSS 4.0 score of 8.6, but the PR:H requirement substantially narrows the attacker population; no public exploit identified at time of analysis and the issue is not listed in CISA KEV. QNAP has shipped fixed builds (QTS 5.2.9.3492 build 20260507 and QuTS hero h5.2.9.3499 build 20260514).
Path traversal in QNAP QTS and QuTS hero NAS operating systems exposes arbitrary file contents to attackers who have already obtained administrator-level access. The root cause (CWE-22) indicates insufficient sanitization of file path inputs, allowing directory escape to reach files outside intended scope. No public exploit code has been identified at time of analysis, and CISA KEV lists no active exploitation - making this a targeted post-compromise risk rather than an opportunistic mass-exploitation scenario. Vendor-released patches address all affected branches as of May 2026.
NULL pointer dereference in QNAP QTS and QuTS hero NAS operating systems enables a remote, administrator-authenticated attacker to trigger a denial-of-service condition. Exploitation requires the attacker to first hold or acquire an administrator account on the target device, after which a crafted request can crash system services. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
NULL pointer dereference in QNAP QTS and QuTS hero NAS operating systems allows remote unauthenticated attackers to crash a network-facing service and cause a denial-of-service condition without any authentication or user interaction. Multiple active OS branches are affected - QTS 5.2.x and QuTS hero h5.2.x through h6.0.x - across a device population that is historically internet-exposed and frequently targeted. No public exploit has been identified and this vulnerability is not listed in CISA KEV, but the zero-authentication, network-accessible attack surface makes DoS attempts trivially repeatable against unpatched devices.
Integer overflow (CWE-190) in QNAP QTS and QuTS hero NAS operating systems allows a remote attacker who has already obtained an administrator account to further compromise system integrity and availability. Affected versions span QTS 5.2.x and QuTS hero h5.2.x through h6.0.x; QNAP released patched builds in February and May 2026. No public exploit code and no CISA KEV listing have been identified at time of analysis, and the mandatory prerequisite of administrator-level access materially constrains real-world exploitability.
Authenticated command injection in QNAP QTS and QuTS hero allows a remote attacker holding administrator credentials to execute arbitrary OS commands on the NAS appliance.

No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
NULL pointer dereference in QNAP QTS and QuTS hero NAS operating systems allows remote unauthenticated attackers to crash a network-facing service and cause a denial-of-service condition without any authentication or user interaction. Multiple active OS branches are affected - QTS 5.2.x and QuTS hero h5.2.x through h6.0.x - across a device population that is historically internet-exposed and frequently targeted. No public exploit has been identified and this vulnerability is not listed in CISA KEV, but the zero-authentication, network-accessible attack surface makes DoS attempts trivially repeatable against unpatched devices.
Integer overflow (CWE-190) in QNAP QTS and QuTS hero NAS operating systems allows a remote attacker who has already obtained an administrator account to further compromise system integrity and availability. Affected versions span QTS 5.2.x and QuTS hero h5.2.x through h6.0.x; QNAP released patched builds in February and May 2026. No public exploit code and no CISA KEV listing have been identified at time of analysis, and the mandatory prerequisite of administrator-level access materially constrains real-world exploitability.
Authenticated command injection in QNAP QTS and QuTS hero allows a remote attacker holding administrator credentials to execute arbitrary OS commands on the NAS appliance. The CVSS 4.0 base score of 8.6 reflects high impact across confidentiality, integrity, and availability, though exploitation requires high privileges (PR:H). No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV; QNAP has released fixed builds across affected QTS and QuTS hero branches.
Authenticated command injection in QNAP QTS and QuTS hero NAS operating systems allows a remote attacker who has already obtained administrator credentials to execute arbitrary OS commands on the appliance. Reported by QNAP itself and tracked as EUVD-2025-210099, the issue affects multiple branches across QTS 5.2.x and QuTS hero 5.2.x, 5.3.x, and 6.0.x and is fixed in builds dated 2026-02-06 through 2026-05-20. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
External control of assumed-immutable web parameters in QNAP NAS software enables remote unauthenticated attackers to achieve low-integrity impact by manipulating parameters the application treats as unmodifiable. The vulnerability requires active user interaction to trigger, limiting opportunistic exploitation. QNAP has released a fix per advisory QSA-26-10; no public exploit code or CISA KEV listing has been identified at time of analysis.
High-severity information disclosure flaw in QNAP QTS NAS operating system versions 5.2.0 through 5.2.7.3256 build 20250913 allows remote unauthenticated attackers to obtain sensitive data over the network with low attack complexity, per CVSS v4.0 vector AV:N/AC:L/PR:N/UI:N rating 9.2. The vendor has released a fix, and notably QuTS hero is explicitly unaffected. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Stack-based buffer overflow in QNAP QTS and QuTS hero NAS operating systems enables an authenticated administrator to corrupt stack memory or crash processes via a network-accessible attack path. Affected versions span QTS 5.2.x and multiple QuTS hero release trains (h5.2.x, h5.3.x, h6.0.x), with vendor-released patches dated February-May 2026. No public exploit code and no CISA KEV listing have been identified at time of analysis, and the mandatory high-privilege prerequisite substantially limits realistic attack surface.
Cross-site scripting in QNAP QTS and QuTS hero operating systems allows remote attackers to bypass security mechanisms and read application data when an authenticated user interacts with attacker-supplied content. The flaw carries a CVSS 4.0 score of 8.7 driven by network reachability, low attack complexity, no required privileges, and high impact across confidentiality, integrity, and availability of the NAS management surface. There is no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
