  "details": "Template::Plugin::HTML versions before 3.103 for Perl allows HTML and JavaScript to be injected.  The 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      \u003ca id='ref' title='[% var | html %]'\u003e  would not be properly escaped. An attacker could insert some limited HTML and JavaScript, for example,      var = \" ' onclick='while (true) { alert(1) }'\"  Note that arbitrary HTML and JavaScript would be difficult to inject, because angle brackets, ampersands and double-quotes would still be escaped.",
