The Universal Import feature in Ghost, a Node.js content management system, is vulnerable to cross-site scripting (XSS) due to improper sanitization of imported content in versions 5.26.0 through 6.54.1. This flaw could allow attackers to inject malicious scripts into post content, potentially compromising user sessions or data integrity. Organizations using affected versions of Ghost should prioritize upgrading to version 6.54.1 to mitigate this risk.
