cwe CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
published Nov 20, 2025
The FluentCRM – Email Newsletter, Automation, Email Marketing, Email Campaigns, Optins, Leads, and CRM Solution plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'fluentcrm_content' shortcode in all versions up to, and including, 2.9.84 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
