CVE-2025-1300: Python Http Server Insecure Cookie Missing Samesitecve-2025-1300-python-http-server-insecure-cookie-missing-samesite

Setting a session cookie via `send_header` without specifying the `SameSite` attribute can expose the application to Cross-Site Request Forgery (CSRF) and other cross-origin attacks. Browsers may send the associated cookie in cross-site requests. Explicitly include `SameSite=Lax` or `SameSite=Strict` in the cookie string.
