AI-suggested

Until a fix is available, users should be cautious when using JS template literals in Golang templates and consider additional manual escaping or validation to mitigate potential XSS risks.

Description

A vulnerability in Golang 1.10 and certain related versions causes improper context tracking across template branches for JavaScript template literals. This leads to incorrect escaping of content within these templates, potentially resulting in cross-site scripting (XSS) vulnerabilities. The issue arises from incorrect tracking of brace depth within template actions inside JS template literals.
