Until an official fix is available, restrict access to high-privilege accounts and monitor for unusual activity related to HttpRequest object usage. Avoid processing untrusted HTTP headers in JavaScript contexts without proper encoding.
Description
CVE-2024-42330 is a critical vulnerability in the HttpRequest object where HTTP headers from server responses are returned as strings directly from server data without proper JavaScript encoding. This flaw allows crafted internal strings to access hidden object properties, potentially leading to severe confidentiality, integrity, and availability impacts.
