• Authenticated attackers with subscriber-level access can inject arbitrary web scripts
• Scripts execute when a user accesses an injected page
• Defenders must verify and update to version 1.7.32 or later
• Review administrator-configured Text attributes for potential XSS vulnerabilities is necessary
