Descriptions

Not all valid JavaScript whitespace characters are considered to be whitespace. Templates containing whitespace characters outside of the character set "\t
\f\r\u0020\u2028\u2029" in JavaScript contexts that also contain actions may not be properly sanitized during execution.

A flaw was found in golang, where not all valid JavaScript white-space characters were considered white space. Due to this issue, templates containing white-space characters outside of the character set "\t
\f\r\u0020\u2028\u2029" in JavaScript contexts that also contain actions may not be properly sanitized during execution.
