Add missing cookie security settings
Cookie Security
1–2 hours

This makes it meaningfully easier for an attacker to hijack authenticated customer sessions, increasing account-takeover risk. On bitbucket.org, most cookies are missing key protections: 2 cookie(s) can be sent over an unencrypted connection (missing the "Secure" flag); 3 cookie(s) can be read by page scripts, including malicious ones (missing "HttpOnly"); 3 cookie(s) don't restrict cross-site requests (missing "SameSite").

OWASP ASVS3.4
Session cookies use Secure, HttpOnly, and SameSite attributes
How to fix this
1Add Secure to every cookie your site sets — this is usually one line in your app's session/cookie config, not a DNS or hosting setting.
2Add HttpOnly to login/session cookies — same place as above, in your app's cookie settings.
3Add SameSite=Lax (or Strict for sensitive cookies) to every cookie.
4This needs a developer — it's a one-line change per cookie in your website's code, not something changeable from a hosting dashboard.
5Re-scan afterward to confirm all three flags are now set.
