    "description": "Template::Plugin::HTML versions through 3.102 for Perl allows HTML and JavaScript to be injected.\n\nThe html_filter function did not escape single quotes. HTML attributes inside of single quotes could be have code injected.  For example, the variable \"var\" in\n\n    <a id='ref' title='[% var | html %]'>\n\nwould not be properly escaped. An attacker could insert some limited HTML and JavaScript, for example,\n\n    var = \" ' onclick='while (true) { alert(1) }'\"\n\nNote that arbitrary HTML and JavaScript would be difficult to inject, because angle brackets, ampersands and double-quotes would still be escaped.",
