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
An issue was discovered in linqi before 1.4.0.1 on Windows. There is /api/DocumentTemplate/{GUID] XSS.

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

A Cross-Site Scripting (XSS) vulnerability exists in the linqi document management system at the /api/DocumentTemplate/{GUID} endpoint in versions prior to 1.4.0.1 on Windows. The endpoint fails to properly sanitize or encode user-supplied input in the GUID parameter, allowing injection of malicious script.

MitigationUpgrade linqi to version 1.4.0.1 or later which contains the vendor patch. Alternatively, implement input validation and output encoding on the affected endpoint as a compensating control.

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. Identify the installed Linqi version
    Locate the version information for the Linqi document management system - typically found in the application itself (About section), installation metadata, or configuration files within the Linqi installation directory on Windows
    Affected if The installed version is anything prior to 1.4.0.1
  2. Confirm the Windows platform
    Verify that the Linqi instance is running on a Windows operating system, as this vulnerability is specific to the Windows version
    Affected if The system is running Linqi on Windows
  3. Check endpoint accessibility
    Verify that the /api/DocumentTemplate/{GUID} API endpoint is exposed and accessible within the environment - this could be internal network, VPN, or direct server access depending on deployment
    Affected if The /api/DocumentTemplate endpoint is reachable and accepts requests

You are affected if your Linqi installation runs on Windows with a version earlier than 1.4.0.1 and the /api/DocumentTemplate endpoint is accessible

Upgrade available Upgrade to 1.4.0.1 or later
Fixed in 1.4.0.1
Interim mitigation

Upgrade linqi to version 1.4.0.1 or later which contains the vendor patch. Alternatively, implement input validation and output encoding on the affected endpoint as a compensating control.

Recommended fix Moderate confidence

1.4.0.1

  1. 1. Verify current Linqi installation version by checking the application or configuration files
  2. 2. Download Linqi version 1.4.0.1 or later from the official source (linqi.help or www.linqi.de)
  3. 3. Create a full backup of the current Linqi installation including database and configuration files
  4. 4. Stop the Linqi service or application
  5. 5. Install version 1.4.0.1 following the official upgrade documentation
  6. 6. Start the Linqi service
  7. 7. Verify the XSS vulnerability in /api/DocumentTemplate/{GUID} endpoint is resolved by testing with a benign script payload
  8. 8. Monitor application logs for any errors post-upgrade
