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 in a FileMaker WebDirect custom homepage could lead to unauthorized access and remote code execution. This vulnerability has been fully addressed in FileMaker Server 22.0.4 and FileMaker Server 21.1.7.

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

A cross-site scripting (XSS) vulnerability exists in the FileMaker WebDirect custom homepage feature that allows attackers to inject malicious scripts into the page. This can lead to unauthorized access through session hijacking and potentially remote code execution if combined with other vulnerabilities.

MitigationUpgrade FileMaker Server to version 22.0.4 or 21.1.7 or later, which contains the complete fix for this 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. Locate FileMaker Server version
    Access the FileMaker Server Admin Console or check the version via the command line (fmserver -v or check the About information in Admin Console)
    Affected if The installed version is before 21.1.7 OR is 22.0.1, 22.0.2, or 22.0.3 (versions 21.x below 21.1.7 and 22.0.1-22.0.3 are vulnerable)
  2. Confirm WebDirect is enabled
    In FileMaker Server Admin Console, navigate to WebDirect settings and verify the WebDirect feature is turned on
    Affected if WebDirect must be enabled for the custom homepage XSS to be exploitable
  3. Identify if custom homepage is configured
    Check the WebDirect publishing settings in Admin Console for a custom homepage URL/path configuration
    Affected if If a custom homepage is configured, the XSS flaw in the custom homepage feature can be triggered; if using default FileMaker-provided homepage, the impact is reduced but the vulnerable code may still be present

You are affected if FileMaker Server version is 21.x before 21.1.7 or is 22.0.1-22.0.3 AND WebDirect with custom homepage feature is enabled and configured
