What an attacker can do

An unauthenticated attacker can craft a Cookie header so Coraza indexes or drops a cookie under a different name or value from the backend application, causing rules targeting REQUEST_COOKIES or REQUEST_COOKIES_NAMES to miss application-visible attacker data. Vendor/CNA’s CVSS 3.1 assessment (base score 4.0/10) rates confidentiality and availability impact as none; integrity impact as low.
