Summary14769: missing cookie attribute
DescriptionIn order to influence security-relevant properties of cookies, they can be provided with various attributes.

The attribute SameSite prevents the sending of cookies in cross-domain-Requests. Unnecessary information disclosures are thus prevented and an additional protection against Cross-Site Request Forgery (CSRF) attacks is established.
For this attribute there are two values:
* The value 'strict' ensures that the cookie is not used at all with Cross-domain requests are sent, not even when clicking on external links.
* The value 'lax' provides cookie transmission for regular GET requests, but prevents CSRF attacks, such as POST requests.
This attribute should be set to 'lax' for all cookies except exceptions.
TagsNo tags attached.

Can be fixed (i think) in config.php :

But we can set is as «the most secure we can» in a new install (in the generated config.php)

Don't know for internal (forced Yii config, config.php can update it).
