> The standard {{Authorization-Bearer}} cookie includes the [SameSite|https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite] attribute in the {{Set-Cookie}} response header, but other cookies for CSRF mitigation, logout processing, and external authentication service integration do not apply the attribute when setting cookies.
> The Java Servlet [Cookie|https://docs.oracle.com/javaee/7/api/javax/servlet/http/Cookie.html] does not support the {{SameSite}} attribute, but the NiFi {{StandardApplicationCookieService}} uses the Spring Response Cookie Builder, which supports the attribute and is capable of applying it to {{Set-Cookie}} headers. Direct use of the Java Servlet {{Cookie}} should be replaced with the implementation approach that supports setting the {{SameSite}} attribute to avoid warnings in modern browsers. In absence of the {{SameSite}} attribute, browsers default to {{{}Lax{}}}, but this can be changed to {{Strict}} in most cases.
