CVE-2023-39318 is a cross-site scripting vulnerability in Go's html/template package. When a template processes HTML-like comment tokens or hashbang comment tokens within a <script> context, the parser can incorrectly interpret the script content. Template actions can consequently be escaped improperly, permitting attacker-controlled content to be rendered in a manner that enables cross-site scripting.
