Exploring the World of ESI Injection

Edge Side Include injection, where ESI tags reflected into a page are executed by the edge cache rather than the browser. ESI variables and functions such as HTTP_COOKIE, add_header and url_decode let an attacker read HttpOnly cookies, rewrite a JSON response Content-Type to text/html, bypass the WAF and take over accounts.
