Before filing issues, please check the following points first:

• [x] Please don't open issues for security issues. Instead, file a report at https://www.npmjs.com/advisories/report?package=handlebars
• [x] Have a look at https://github.com/handlebars-lang/handlebars.js/blob/master/CONTRIBUTING.md
• [x] Read the FAQ at https://github.com/handlebars-lang/handlebars.js/blob/master/FAQ.md
• [x] Use the jsfiddle-template at https://jsfiddle.net/4nbwjaqz/4/ to reproduce problems or bugs

This will probably help you to get a solution faster. For bugs, it would be great to have a PR with a failing test-case. https://jsfiddle.net/4qvo810e/ I want to insert {{xxx}}} and run with {xxx:1},expect result 1}, but throw error

handlebars.js:2992 Uncaught Error: Parse error on line 1:
{{xxx}}}
------^
Expecting 'CLOSE', 'OPEN_SEXPR', 'ID', 'STRING', 'NUMBER', 'BOOLEAN', 'UNDEFINED', 'NULL', 'DATA', got 'CLOSE_UNESCAPED'
