Embedding JavaScript statements that are dynamically derived from user input into <script> tags would be extremely risky; it is essentially impossible to reliably distinguish harmless snippets of code from dangerous ones. Enclosing in quotes and backslash-escaping the inserted string ensures that the JavaScript parser interprets the string as a single string literal as intended. We must escape quotes and line feed characters because they could be interpreted as the end of the string literal and permit an escape from the quote attack. We also must escape the backslash; otherwise the attacker could provide a single backslash, which would escape the quote that was intended to end the string literal. After that, the sense of inside and outside string literals is reversed, and the attacker may be able to cause script execution if he controls another string that is inserted later on. The escaping of the angle bracket characters is necessary because otherwise an attacker could cause arbitrary script execution by injecting the following (into the msg_text variable in the example at the beginning of this section): foo</script><script>evil-script;</script><script> After substitution, the HTML evaluated by the browser would be the following (the extra new lines were inserted for formatting reasons): <script> var msg_text = 'foo</script> <script>evil-script;</script> <script>' // ... // do something with msg_text </script> Somewhat surprisingly, this HTML document does in fact result in the execution of evil-script;. The reason is that the browser first parses the document as HTML, and only later passes text enclosed in <script> tags to the JavaScript interpreter in other words, the HTML parser does not respect or care about the delimiters of JavaScript string literals. Thus, the HTML fragment will be parsed into three separate <script> tags. The first script tag contains invalid JavaScript and would result in a syntax error.
