CVE-2026-47786	Unauthenticated remote command execution in QNAP HybridDesk Station (HD Station) lets network attackers run arbitrary operating system commands on affected QNAP NAS devices that have the optional desktop/multimedia add-on installed. The root cause is an OS command injection (CWE-78) rated 9.3 under CVSS v4.0 (AV:N/AC:L/PR:N/UI:N), so no credentials, user interaction, or special preconditions are required; the vendor has fixed it in HybridDesk Station 4.2.23 (4.2 branch) and 4.3.4 (4.3 branch). No public exploit code or confirmed active exploitation has been identified at time of analysis, but real-world risk is governed by whether HD Station is installed and whether its interface is reachable from the attacker's network position (LAN versus internet-facing), as the specific vulnerable feature and input parameter have not been disclosed.	CRITICAL	9.3	1.4%	48
CVE-2026-50612	Authenticated remote attackers holding a valid QuMagie account can exploit a Unix symbolic-link following flaw (CWE-61) in QNAP's QuMagie photo and media management application to compromise the security of the underlying NAS system. The vulnerable code follows attacker-influenced symlinks during file operations, allowing file reads and writes outside the intended media library boundaries, with the assessed vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) reflecting high confidentiality, integrity and availability impact that crosses a security scope boundary - essentially escaping the application sandbox to reach the host NAS. Exploitation requires the attacker to first obtain a QuMagie user account (PR:L) and the ability to place a symlink or control a path the app will follow; no victim interaction is needed. There is no public exploit identified at time of analysis, and QNAP has released a fix in QuMagie 2.9.2 and later.	CRITICAL	9.4	0.5%	47
CVE-2026-50619	Path traversal in QNAP Qsirch lets remote attackers reach the full-text search application without authentication and read files and system data outside the intended directory structure on the host NAS. The vendor states the flaw is fixed in Qsirch 7.0.3.0 and later, so only NAS devices running an earlier build of this optional app - and exposing its web interface to the attacker's network path - remain at risk; no public exploit code and no confirmed active exploitation were identified at time of analysis. Our independent assessment scores the issue at CVSS 3.1 8.6-class severity on the confidentiality axis (C:H/I:N/A:N), meaning the realistic worst case is read-only disclosure of sensitive files rather than the file modification or service disruption implied by the higher input CVSS 4.0 score of 9.3.	CRITICAL	9.3	0.6%	47
CVE-2026-34006	Missing authentication in sMedio DTCP MOVE before version 1.4.5 lets remote, unauthenticated attackers reach critical functions of the DTCP-IP content-transfer service (sMedioDTCPServer) running on QNAP NAS devices, yielding high impact to confidentiality, integrity and availability (vendor CVSS 4.0 base 9.3; independent assessment CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The vendor has shipped a fixed release (1.4.5 and later), and no public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis. Real-world exposure is limited mainly by deployment scarcity - this is an optional, niche QNAP add-on rather than a default NAS service - and by whether the affected service is network-reachable rather than confined behind NAT or a segmented LAN.	CRITICAL	9.3	0.5%	47
CVE-2026-39997	QNAP HybridDesk Station (HD Station) before 4.2.22 contains a missing authentication flaw in a critical function, allowing unauthenticated attackers on an adjacent network to gain access to the system. Exploitation is constrained by a specific attack precondition and passive user interaction, and only QNAP NAS devices with the optional HD Station app installed and enabled are exposed. The vendor has released HybridDesk Station 4.2.22 and later as a fix; no public exploit was identified at time of analysis.	HIGH	8.9	0.4%	45
CVE-2026-34015	Authenticated path traversal in QNAP Video Station before 5.8.8 allows a remote attacker with a valid low-privileged user account to read arbitrary files and system data outside the intended application directory. The flaw is CWE-22 and requires network access with low complexity and no user interaction, but the PR:L vector means an attacker must first hold a Video Station account, limiting mass exploitation. no public exploit identified at time of analysis, and QNAP has released Video Station 5.8.8 as the fix. The vendor CVSS 4.0 score is 8.7, but independent assessment scopes impact to confidentiality only, so it is a genuine moderate-priority issue rather than a top-tier emergency.	HIGH	8.7	0.5%	44
CVE-2026-53882	Improper link resolution (CWE-59) in QNAP Virtualization Station before 4.1.1.130 allows an authenticated remote attacker with a low-privilege user account to manipulate a symbolic link that is later followed by a privileged file operation, achieving high confidentiality, integrity, and availability impact (CVSS 8.7). This is a credible, elevated-priority issue for environments running the Virtualization Station (QKVM) add-on, though not a drop-everything emergency; exploitation requires the app to be installed and the attacker to hold a valid low-privilege account, and no public exploit code or active exploitation (KEV) has been identified at time of analysis. Upgrade to 4.1.1.130 or later to remediate.	HIGH	8.7	0.5%	44
CVE-2026-44084	Unauthenticated remote attackers can read sensitive data from QNAP NAS devices running the optional Video Station (VideoStationPro) application prior to 5.8.8 by exploiting a CWE-639 authorization bypass through a user-controlled key. The vendor rates the flaw 8.7 under CVSS 4.0 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) and our independent assessment scores it 7.5 under CVSS 3.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting a confidentiality-only impact with no integrity or availability loss. Exploitation requires Video Station to be installed and network-reachable on a QTS/QuTS NAS, and no public exploit code or CISA KEV listing was identified at time of analysis, so this is a high-priority information-disclosure issue rather than a confirmed actively exploited one.	HIGH	8.7	0.4%	44
CVE-2026-41545	Authenticated path traversal in QNAP QuMagie lets an attacker who already holds a QuMagie administrator account read files and system data outside the intended media library on the underlying QNAP NAS. The flaw is remote, network-reachable and low-complexity, but the PR:H privilege requirement in the CVSS vector means it is not exploitable by anonymous users against default installations; no public exploit code has been identified at time of analysis and the issue is not listed in CISA KEV. QNAP has shipped a fix in QuMagie 2.9.1 and later, so exposure is limited to NAS deployments still running older QuMagie builds and reachable by an admin-level account.	HIGH	8.6	0.5%	44
CVE-2026-34008	Incorrect permission assignment (CWE-732) in QNAP Notes Station 3 allows a local attacker who already holds a valid low-privileged account on the NAS to abuse an insecurely permissioned critical resource created by the application, resulting in full compromise of confidentiality, integrity, and availability of the affected system's data. Only QNAP NAS devices with the Notes Station 3 app installed are affected, and exploitation is not possible remotely by an unauthenticated attacker - it requires local access plus a user account (AV:L, PR:L per CVSS:4.0 vector and the assessed CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). No public exploit code has been identified at time of analysis, and EPSS/KEV data were not provided; QNAP has released a fix in Notes Station 3 3.9.11 and later.	HIGH	8.5	0.1%	43
CVE-2026-34009	QNAP Notes Station 3 versions prior to 3.9.11 fail to properly compartmentalize privileged functionality, so an attacker who already holds a local administrator account on the NAS can step outside the intended isolation boundary and compromise the confidentiality, integrity, and availability of the system. The vulnerability is strictly local (AV:L) and requires high privileges (PR:H) with no user interaction (UI:N), meaning it is not remotely reachable and cannot be triggered by an unauthenticated or low-privileged user; realistic abuse is limited to malicious privileged insiders or privilege/isolation escape following an earlier compromise. QNAP has released a fix in Notes Station 3 3.9.11 and later, and there is no public exploit code or CISA KEV entry identified at time of analysis, so this is a moderate-priority, high-barrier issue rather than an urgent widespread threat.	HIGH	8.4	0.1%	42
CVE-2026-34014	Incorrect permission assignment in QNAP Download Station (all builds prior to 5.10.1.312 or 5.11.2.321) lets a local attacker who already holds an administrator account on the NAS escalate that foothold into full compromise of the device's confidentiality, integrity and availability. The issue is access-gated rather than remotely reachable: the CVSS:4.0 vector marks local attack vector (AV:L) and high privileges (PR:H), so a remote or unauthenticated attacker cannot trigger it and no user interaction is required once admin access exists. No public exploit code has been identified at time of analysis and the flaw is not confirmed as actively exploited (CISA KEV), but vendor-released fixes are available, so the practical risk sits with deployments that share, weakly protect, or already have compromised QNAP admin credentials.	HIGH	8.4	0.1%	42
CVE-2026-26243	Path traversal in QNAP Qsync Central allows an attacker who already holds a valid Qsync Central user account to read files and system data outside the intended directory scope on the NAS. The flaw originates from improper limitation of a pathname to a restricted directory (CWE-22); because the CVSS vector specifies PR:L, exploitation is authenticated - remote unauthenticated Internet attackers cannot reach it against default configurations. Impact is assessed as information disclosure of high confidentiality value rather than code execution or data destruction, and no public exploit code has been identified at time of analysis. All versions prior to Qsync Central 5.0.0.6, 5.1.0.2, and 5.2.0.4 are affected, and QNAP has released fixed builds on each of these branches.	HIGH	7.2	0.5%	37
CVE-2026-34007	QNAP Notes Station 3 versions prior to 3.9.11 contain an OS command injection flaw (CWE-78) that permits unauthenticated network attackers to run arbitrary commands on a NAS where the optional Notes Station 3 add-on is installed and reachable. The vendor's CVSS 4.0 vector (6.9) indicates low confidentiality, integrity, and availability impact, suggesting the injected commands execute in a constrained context rather than granting full system control. No public exploit code has been identified at time of analysis, and the primary exposure is limited to internet-facing or broadly accessible NAS instances running the vulnerable add-on.	MEDIUM	6.9	1.6%	36
CVE-2026-26244	SQL injection in QNAP Video Station (versions prior to 5.8.8) allows a remote attacker who already holds a valid NAS user account to read sensitive data from the application's backend database through the Video Station web interface. The flaw is an authenticated issue (CVSS PR:L), and the independent assessment bounds the impact to confidentiality only (C:H), meaning it does not by itself provide code execution or service disruption despite the description's broader wording. No public exploit code was identified at time of analysis, and the vendor has released a fix in Video Station 5.8.8 and later.	HIGH	7.1	0.4%	36
