Add the header with a max-age of at least 1 year. - **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'. - **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN. - **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter. - **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features. - **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis. - **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'. - **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers. - **[WARNING]** X-Powered-By header reveals technology stack — This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it. - **[WARNING]** Server header reveals version information — The Server header discloses the software version, aiding attackers in targeting known vulnerabilities. Remove the version number. - **[INFO]** Domain is not in the Chrome HSTS preload list (status: unknown) — Submit your domain to hstspreload.org to close the trust-on-first-use gap. Requires a preload-ready HSTS header (max-age=31536000+, includeSubDomains, preload). ### Content Security Policy (F — 0/100) *No enforcing CSP policy found* - **[CRITICAL]** No Content-Security-Policy header found — CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading. ### TLS & Certificates (A+ — 100/100) *TLS 1.3, 8 checks passed* - **[PASS]** TLS 1.3 is used - **[PASS]** Strong cipher suite is used - **[PASS]** HTTP/2 is negotiated - **[INFO]** OCSP stapling not enabled — Without stapling, the browser performs a separate OCSP roundtrip on first connection -- adding latency and leaking the visited host to the CA. Enable OCSP stapling on your TLS server. - **[PASS]** Certificate is valid (expires in 77 days) - **[PASS]** Certificate chain has 4 certificates - **[PASS]** Certificate uses modern signature algorithm - **[PASS]** Certificate covers 1 domain(s) - **[PASS]** Certificate is issued by a trusted CA ### Cookie Security (A+ — 95/100) *5 cookies analyzed, 14 checks passed* - **[PASS]** Cookie 'XSRF-TOKEN' has the Secure flag - **[WARNING]** Cookie 'XSRF-TOKEN' is missing the HttpOnly flag — Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft. - **[PASS]** Cookie 'XSRF-TOKEN' has SameSite=Lax - **[PASS]** Cookie 'yvid' has the Secure flag - **[PASS]** Cookie 'yvid' has the HttpOnly flag - **[PASS]** Cookie 'yvid' has SameSite=Lax - **[PASS]** Cookie 'fvurl' has the Secure flag - **[PASS]** Cookie 'fvurl' has the HttpOnly flag - **[PASS]** Cookie 'fvurl' has SameSite=Lax - **[PASS]** Cookie 'original-referrer' has the Secure flag - **[PASS]** Cookie 'original-referrer' has the HttpOnly flag - **[PASS]** Cookie 'original-referrer' has SameSite=Lax - **[PASS]** Cookie 'youcan_session' has the Secure flag - **[PASS]** Cookie 'youcan_session' has the HttpOnly flag - **[PASS]** Cookie 'youcan_session' has SameSite=Lax ### Cookie Hygiene (A+ — 95/100) *1 hygiene issue(s) across 5 cookie(s)* - **[INFO]** 1 cookie(s) live for more than 1 year — Cookies with Max-Age or Expires more than 1 year out are effectively permanent on the user's device. Most session and preference cookies don't need that lifetime. Long-lived tracking cookies also carry a heavier compliance load (GDPR / CCPA). Affected: yvid. ### WAF / Bot Protection (B — 75/100) *No WAF detected via response headers* - **[INFO]** No WAF detected — Response headers don't match any known WAF or bot-management product. Sites exposed to abuse (login, signup, payment) typically benefit from a WAF such as Cloudflare, Akamai, AWS WAF, or Imperva. ### security.txt (C — 60/100) *No security.txt file found* - **[INFO]** No security.txt file found — security.txt (RFC 9116) provides a standardized way for security researchers to report vulnerabilities. Create one at /.well-known/security.txt with at least a Contact field. ### Cross-Origin Tab Safety (D — 60/100) *6 of 6 new-tab link(s) missing rel=noopener* - **[WARNING]** 6 link(s) open in a new tab without rel=noopener — Without rel="noopener", the destination tab can navigate the original tab via window.opener -- a reverse-tabnabbing phishing primitive. Modern browsers default to noopener since Chrome 88 / Firefox 79 / Safari 12.1, but explicit rel="noopener noreferrer" remains the documented best practice for older browsers, in-app webviews, and security scanners. ### CSP Inline-Style Readiness (D — 60/100) *70 inline style attribute(s) detected* - **[WARNING]** 70 inline style attribute(s) detected — Each `style=""` attribute forces `style-src 'unsafe-inline'` in any Content-Security-Policy, which negates most of CSP's XSS-mitigation value. 70 inline style(s) is high. Affected element types include: img, yc-section, yc-slider, yc-modal, label. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win. ### Trusted Types (XSS Sink Hardening) (A+ — 100/100) *No CSP header -- Trusted Types check is N/A* - **[PASS]** No CSP header found -- Trusted Types check is N/A ### Bot Challenge Detection (A+ — 100/100) *Scan reached real page content (no bot-protection interstitial)* - **[PASS]** No bot-protection interstitial detected -- the rest of the report reflects the real page ### Soft-404 Detection (A+ — 100/100) *No soft-404 patterns detected in page title or headings* - **[PASS]** No soft-404 patterns detected in page title or headings ### Empty Page Detection (A+ — 100/100) *Page has substantive body text and no placeholder / template-leak signals* - **[PASS]** Page has substantive body text and no placeholder / template-leak signals ### Geo-Restriction Detection (A+ — 100/100) *No geo-restriction signals detected -- scan reached the page from an allowed region* - **[PASS]** No geo-restriction detected ### Maintenance Mode Detection (A+ — 100/100) *No maintenance-mode signals detected -- scan reached a normal page* - **[PASS]** No maintenance-mode signals detected ### Subresource Integrity Adoption (F — 30/100) *0% SRI adoption (0/91 third-party resources)* - **[WARNING]** SRI adoption: 0/91 third-party resources protected (0%) — Of 91 third-party `
