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
HP Color LaserJet Pro M280-M281 Multifunction Printer series (before v. 20190419), HP LaserJet Pro MFP M28-M31 Printer series (before v. 20190426) may have an embedded web server potentially vulnerable to reflected XSS in wireless configuration page.

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 · high confidence

Reflected XSS vulnerability in the embedded web server wireless configuration page of HP Color LaserJet Pro M280-M281 Multifunction Printer series (before v.20190419) and HP LaserJet Pro MFP M28-M31 Printer series (before v.20190426). The vulnerability allows injection of malicious scripts through unsanitized user input in the wireless settings parameters.

MitigationUpdate printer firmware to version 20190419 or later for M280-M281 series, and version 20190426 or later for M28-M31 series to remediate the reflected XSS vulnerability.

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 printer model number
    Access the printer's embedded web server (EWS) by entering the printer's IP address in a browser, or print a configuration/information page from the printer control panel. Locate the model identifier (such as T6b80a, T6b81a, T6b82a, T6b83a for M280-M281 series, or W2g54a, W2g55a, Y5s53a, Y5s55a for M28-M31 series).
    Affected if The model number matches one of the affected product codes: T6b80a, T6b81a, T6b82a, T6b83a, W2g54a, W2g55a, Y5s53a, or Y5s55a.
  2. Check the installed firmware version
    In the printer's embedded web server, navigate to the General tab or Information/Status section to view the firmware version. Alternatively, print a configuration page from the control panel to see the firmware date or version number.
    Affected if For M280-M281 series (T6b80a-T6b83a): firmware version date is before 2019-04-19. For M28-M31 series (W2g54a, W2g55a, Y5s53a, Y5s55a): firmware version date is before 2019-04-26.
  3. Confirm the embedded web server is enabled
    Access the printer's embedded web server via its IP address on the network. If the login page or printer status page loads, the web server is enabled. This can also be verified in the printer's network settings or via the HP Embedded Web Server configuration.
    Affected if The embedded web server is accessible and responds to HTTP requests on the network.
  4. Verify wireless settings page is accessible
    In the embedded web server, navigate to the Networking or Wireless settings section (typically under Settings > Network or Wireless). The vulnerability exists in the wireless configuration page where wireless network parameters can be entered or modified.
    Affected if The wireless configuration page is accessible and accepts user input for wireless network settings such as SSID or other wireless parameters.

The environment is affected if the printer model matches one of the eight affected product codes and its firmware version predates the threshold date (2019-04-19 for M280-M281 series or 2019-04-26 for M28-M31 series) while the embedded web server and wireless settings page are accessible.
