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 the vcita plugin installation
    Check your WordPress site's wp-content/plugins/ directory for the vcita Online Booking & Scheduling Calendar plugin folder, or use the WordPress admin Plugins page to identify if the plugin is installed
    Affected if The plugin folder exists in the plugins directory or appears in the WordPress admin plugins list
  2. Determine the installed version
    Access the plugin details through WordPress admin (Plugins > Installed Plugins > vcita) or inspect the plugin header in its main PHP file to read the Version field
    Affected if The reported version number is less than 4.4.3 (for example, 4.4.2, 4.4.1, 4.4.0, or earlier)
  3. Identify accessible booking or scheduling endpoints
    Review your website for pages or URLs that use the vcita plugin functionality, such as booking forms, scheduling widgets, or calendar integration points
    Affected if Publicly accessible vcita endpoints exist that accept user input (such as query parameters or form submissions)
  4. Test for reflected input without encoding
    Submit a harmless test string containing special characters (such as <script>alert(1)</script> or similar) as a parameter on vcita-enabled pages and observe whether the exact string appears unescaped in the page response
    Affected if User-supplied input is reflected back in the HTML output without proper encoding or sanitization
