The record

WebDyne versions from 2.014 before 3.022 for Perl reflect request parameters unescaped into form field values, allowing cross-site scripting. The textfield, password_field and filefield tags fill their value attribute from the request parameter of the same name. WEBDYNE_CGI_AUTOESCAPE, which controls escaping of these values, defaults to off. From 2.022, WebDyne::HTML::Tiny also replaced its entity_encode method with one that returns its input unchanged, so enabling WEBDYNE_CGI_AUTOESCAPE has no effect. A remote attacker can inject script into any page using these tags through a crafted link.
