Description
CVE-2026-23947 had an incomplete fix
While the current jsStringEscape function properly handles single quotes ('), double quotes (") and other characters, it fails to sanitize * and / characters. This allows attackers to break out of JavaScript comment blocks using */ sequences and inject arbitrary code into generated files.
