Short explanation

An unauthenticated Stored Cross-Site Scripting vulnerability has been identified in the Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress. Versions up to and including 4.5.14 are affected due to insufficient input sanitization and output escaping via the 'ref' parameter, allowing unauthorized attackers to inject arbitrary web scripts.
