Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A cross-site scripting (XSS) vulnerability has been reported to affect Download Station. If a remote attacker gains a user account, they can then exploit the vulnerability to bypass security mechanisms or read application data. We have already fixed the vulnerability in the following versions: Download Station 5.10.0.305 ( 2025/09/16 ) and later Download Station 5.10.0.304 ( 2025/09/08 ) and later

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Download Station contains a stored cross-site scripting (XSS) vulnerability. An authenticated remote attacker with a valid user account can inject malicious scripts through the application to bypass security mechanisms or access sensitive application data.

MitigationUpgrade Download Station to version 5.10.0.305 (released 2025/09/16) or 5.10.0.304 (released 2025/09/08) or later. Since the vulnerability requires an attacker to first obtain a user account, enforce strong password policies and limit account creation privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate Download Station version in QNAP interface
    Log into the QNAP admin console, navigate to App Center, find Download Station in the installed applications list, and record the version number displayed.
    Affected if The displayed version matches 5.10.0.291 or falls between 5.10.0.292 and 5.10.0.304 inclusive.
  2. Check Download Station version via QNAP CLI
    Access the QNAP NAS via SSH or shell, then run the command: cat /share/CACHEDEV1_DATA/.qpkg/DownloadStation/version. Alternatively, use: qpkg_cli -i DownloadStation to retrieve version information.
    Affected if The retrieved version matches 5.10.0.291 or falls between 5.10.0.292 and 5.10.0.304 inclusive.
  3. Verify Download Station web interface accessibility
    Confirm that the Download Station web portal is accessible remotely or internally by accessing the URL typically at https://[NAS-IP]/download/, or via the main QNAP portal.
    Affected if The web interface is exposed and the installed version is within the affected range.
  4. Confirm valid user accounts exist
    In the QNAP admin interface, navigate to Control Panel > Privilege > Users to review existing user accounts that could potentially exploit this vulnerability.
    Affected if Any valid user account exists in the system while Download Station version is within the affected range.

The environment is affected if Download Station is installed and its version is 5.10.0.291 through 5.10.0.304, and at least one valid user account exists in the QNAP system.
