Reject insecure SameSite=None cookies
Use of cookies with SameSite set to None without the Secure attribute is no longer supported. Any cookie that requests SameSite=None but is not marked Secure will be rejected. This feature started rolling out to users of Stable Chrome on July 14, 2020. See SameSite Updates for a full timeline and details. Cookies delivered over plaintext channels may be cataloged or modified by network attackers. Requiring secure transport for cookies intended for cross-site usage reduces this risk.
