Summary

ghtml Cross-Site Scripting (XSS) vulnerability

Details

Summary

It is possible to introduce user-controlled JavaScript code and trigger a Cross-Site Scripting (XSS) vulnerability in some cases.

Actions Taken

Updated the documentation to clarify that while ghtml escapes characters with special meaning in HTML, it does not provide comprehensive protection against all types of XSS attacks in every scenario. This aligns with the approach taken by other template engines. Developers should be cautious and take additional measures to sanitize user input and prevent potential vulnerabilities. More reading: https://cheatsheetseries.owasp.org/cheatsheets/CrossSiteScriptingPreventionCheat_Sheet.html
The backtick character (`) is now also escaped to prevent the creation of strings in most cases where a malicious actor somehow gains the ability to write JavaScript. This does not provide comprehensive protection either.
