Frequently Asked Questions
What must an attacker be able to do to exploit this issue?
The CVSS vector indicates local access, low privileges, high attack complexity, and user interaction are required. The described impact involves exploiting missing cookie protections to support CSRF, XSS-based session hijacking, or unauthorized access.
Which cookie protections are reported as missing or insufficient?
The issue concerns missing or insecure SameSite, HttpOnly, Secure, and restrictive Path cookie attributes. These attributes help limit cross-site request abuse, client-side script access to cookies, unencrypted cookie transmission, and overly broad cookie scope.
