  "details": "Web::Simple versions before 0.037 for Perl do not escape single quotes in HTML::Tags output.  HTML::Tags and XML::Tags escape a plain string value by replacing only \u0026, \", \u003c and \u003e with entities. A value interpolated into a single-quoted attribute, as in \u003ca href='$value'\u003e, can therefore close the attribute and add new ones, such as an event handler. Double-quoted attributes are not affected.  An attacker who controls a value that an application interpolates into a single-quoted attribute can inject script into the generated page.",
