 Hey Leon,

Your rule id point to an outdated version of the Core Rule Set (2.2.x)

I suggest you update to the Core Rule Set 3.0.2 version and the alerts
should disappear as the rules in question are no longer part of the
default installation.

It is generally possible to exclude individual cookies from a given rule.
But the syntax is slightly different from the one you presented. I suggest
you follow the tutorial about the handling of false positives at

Good luck!

Christian
