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

Reflected XSS vulnerability in the Fluent CRM WordPress plugin allows attackers to inject malicious scripts via unsanitized user input that gets rendered in web pages without proper encoding. The vulnerability affects versions up to and including 3.1.7.

MitigationUpdate Fluent CRM to the latest version beyond 3.1.7 which contains the security patch, or deploy WAF rules to filter XSS attack payloads as an interim measure.

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. Check Fluent CRM plugin version
    In WordPress admin, go to Plugins > Installed Plugins > Fluent CRM and look at the Version field, or check the version in the plugin's main PHP file (fluent-crm.php) in wp-content/plugins/fluent-crm/
    Affected if The displayed version is 3.1.7 or lower, indicating the unpatched version is installed
  2. Confirm plugin is active
    In WordPress admin, verify that Fluent CRM appears in the Plugins list with an 'Active' status, or query the wp_options table for option_name = 'fluentcrm_active_modules'
    Affected if The plugin is active and the version is 3.1.7 or lower
  3. Identify if public-facing forms are enabled
    Check Fluent CRM settings at Fluent CRM > Settings > General to see if public subscription forms or landing pages are enabled, which would expose the reflection point
    Affected if Public forms or any feature that renders user input on web pages is enabled on an unpatched version
  4. Review web server logs for XSS attempt indicators
    Search access logs (typically in /var/log/nginx/ or /var/log/apache2/) for unusual script tags, javascript:, or HTML event handlers in URLs containing 'fluent-crm' or 'fluentcrm' paths
    Affected if Suspicious XSS payloads are found in logs targeting Fluent CRM endpoints on an unpatched version

You are affected if Fluent CRM plugin version 3.1.7 or lower is installed and active, particularly if public-facing features that render user input are enabled.
