bug: fix template use of structure with untrusted data Looks like an xSS bug with an early version of the template that was fixed in the code but never in the deployed tracker. It has been a while since this particular construct has been in the classic template which is the base for the tracker. This has been fixed on the deployed tracker as well. reported by 4bug of ChaMd5 Security Team H1 Group

try:
    from html import escape as html_escape_  # python 3

    def html_escape(string, quote=False):
        # html_escape under python 3 sets quote to true by default
        # make it python 2 compatible
        return html_escape_(string, quote=quote)
except ImportError:
    # python 2 fallback
    from cgi import escape as html_escape  # noqa: F401
