Security

CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading.

Of 64 third-party `<script>` / `<link rel=stylesheet>` resources, 1 (1%) declare a Subresource Integrity hash via the `integrity=` attribute. SRI binds the page to the exact bytes of the third-party resource: if the CDN is compromised, attacker-modified bytes won't match the declared hash and the browser refuses to execute the resource. Missing SRI on (first 5 examples): - https://connect.facebook.net/signals/config/2912487648984100?v=2.9.427&r=stable&domain=shopavara.com&hme=766752a074f0cb0756dd3275a46fdecbcfe3de1ab8f573546734b619e44d384f&ex_m=118%2C241%2C171%2C27%2C82%2C83%2C162%2C78%2C77%2C11%2C181%2C102%2C20%2C153%2C141%2C46%2C85%2C90%2C149%2C176%2C183%2C8%2C4%2C5%2C7%2C6%2C3%2C103%2C115%2C32%2C17%2C31%2C18%2C33%2C34%2C35%2C37%2C55%2C163%2C87%2C126%2C22%2C24%2C51%2C47%2C49%2C48%2C95%2C104%2C108%2C124%2C160%2C164%2C53%2C125%2C29%2C26%2C133%2C79%2C43%2C166%2C165%2C167%2C157%2C155%2C30%2C42%2C66%2C123%2C178%2C80%2C21%2C128%2C93%2C76%2C23%2C97%2C98%2C130%2C96%2C151%2C150%2C154%2C109%2C177%2C180%2C41%2C56%2C127%2C54%2C161%2C72%2C185%2C110%2C184%2C210%2C255%2C84%2C274%2C273%2C272%2C14%2C25%2C28%2C40%2C62%2C117%2C68%2C10%2C73%2C111%2C112%2C113%2C119%2C144%2C38%2C36%2C146%2C147%2C148%2C143%2C142%2C172%2C86%2C175%2C173%2C174%2C57%2C69%2C67%2C137%2C19%2C179%2C52%2C324%2C325%2C326%2C323%2C340%2C362%2C248%2C237%2C70%2C238%2C236%2C365%2C356%2C59%2C249%2C121%2C145%2C92%2C135%2C61%2C134%2C140%2C139%2C65%2C74%2C168%2C88%2C89%2C129%2C44%2C39%2C60%2C63%2C114%2C182%2C1%2C138%2C16%2C136%2C12%2C2%2C64%2C105%2C15%2C75%2C71%2C132%2C101%2C100%2C187%2C188%2C106%2C107%2C9%2C116%2C186%2C58%2C158%2C99%2C91%2C81%2C131%2C120%2C169%2C50%2C159%2C0%2C94%2C152%2C156%2C170%2C45%2C122%2C13%2C189 - https://connect.facebook.net/en_US/fbevents.js - https://www.googletagmanager.com/gtag/js?id=G-X323YK7DW1&cx=c&gtm=4e6al0 - https://ct.pinterest.com/static/ct/token_create.js - https://analytics.tiktok.com/i18n/pixel/static/identify_9fbdaf50.js Fix: add `integrity="sha384-..."` and `crossorigin="anonymous"` attributes. Generators: srihash.org, or in-browser via `await crypto.subtle.digest('SHA-384', bytes)`. Cache-bust the resource URL when you change versions, since the integrity hash will mismatch with old cached bytes.

Without SRI, if this CDN is compromised, attackers could inject malicious code.

Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.

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.

Introspection lets clients query the GraphQL server for its complete schema -- every type, field, argument, and resolver name. Convenient during development; on production, an attacker uses it as a free recon tool to map the entire data graph. Disable in production unless your API is intentionally public-spec.

The Permissions-Policy header explicitly declares policies for 9/10 high-risk features. Covered: camera, microphone, geolocation, payment, usb, serial, accelerometer, gyroscope, magnetometer Not declared (default-allow): midi The non-declared features fall back to their spec-default policy (usually `self`), which means an XSS-injected or compromised iframe could request them. For features the page genuinely doesn't use, declare `feature=()` to fully close them.

Full URL Referer header on same-origin requests; no Referer at all on cross-origin. Strong privacy posture; same-origin analytics still work.

Consider adding a security.txt at /.well-known/security.txt.

The server advertises HTTP/3 via Alt-Svc for faster connections on mobile networks.
