CWE-1275: Sensitive Cookie with Improper SameSite Attribute

Variant Incomplete

The SameSite attribute for sensitive cookies is not set, or an insecure value is used.

How to prevent it (1 mitigation)
  1. Implementation

    Set the SameSite attribute of a sensitive cookie to "Lax" or "Strict". This instructs the browser to apply this cookie only to same-domain requests, which provides a good Defense in Depth against CSRF attacks. When the "Lax" value is in use, cookies are also sent for top-level cross-domain navigation via HTTP GET, HEAD, OPTIONS, and TRACE methods, but not for other HTTP methods that are more likely to cause side-effects of state mutation.
