What to do

AI-suggested

Organizations should immediately assess their Grav CMS installations to determine if version 1.7.45 or earlier vulnerable versions are in use. Until an official patch is released, implement strict input validation and sanitization on all user-supplied data to prevent script injection. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Enable HTTP-only and Secure flags on cookies to reduce the risk of session hijacking. Educate users and administrators about the risks of clicking untrusted links or interacting with suspicious content that could trigger the XSS payload. Monitor web server logs and application behavior for unusual requests or script injections. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS attack patterns specific to Grav CMS. Stay informed about updates from Grav CMS developers and apply patches promptly once available. Conduct regular security audits and penetration testing focused on input handling and client-side script execution.
