Top issues to fix
5 issues found · 2 high priority

Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
1 cookie without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
Meta description longer than 160 characters
SEOTrim the meta description to under 160 characters to avoid truncation in search results.
3 broken links on the page
