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 on Epson Expression Home XP255 20.08.FM10I8 devices. POST requests don't require (anti-)CSRF tokens or other mechanisms for validating that the request is from a legitimate source. In addition, CSRF attacks can be used to send text directly to the RAW printer interface. For example, an attack could deliver a worrisome printout to an end user.

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

The Epson Expression Home XP255 with firmware 20.08.FM10I8 lacks CSRF protection on POST requests. This allows attackers to forge authenticated print jobs and send arbitrary content directly to the printer's RAW interface, enabling delivery of unwanted or deceptive printouts to victims.

MitigationNetwork isolate the printer or restrict access to trusted networks only; contact Epson for firmware updates if available.

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
    Access the printer's web interface or check the device label to confirm it is an Epson Expression Home XP255
    Affected if The device is an Epson Expression Home XP255
  2. Check firmware version
    Access the printer web interface (typically http://[printer-ip]/ or through Epson Connect) and navigate to the firmware or status section to retrieve the installed firmware version
    Affected if The firmware version is 20.08.FM10I8 or lower
  3. Confirm web interface is enabled
    Attempt to access the printer web interface via HTTP on the local network. Check if the login page or status page loads
    Affected if The web interface is accessible and responds to HTTP requests
  4. Verify network exposure
    Determine if the printer IP is accessible from network segments outside of a restricted VLAN or isolated printer network
    Affected if The printer is reachable from untrusted network segments

A user is affected if they have an Epson Expression Home XP255 printer running firmware version 20.08.FM10I8 with the web interface enabled and accessible on a network where an attacker could trick an authenticated user into submitting requests.
