  "details": "CGI versions before 5.00 for Perl allow the POSTDATA, PUTDATA, PATCHDATA and XForms:Model parameters to be set from the query string or form fields.  CGI stores a non-form request body under POSTDATA, PUTDATA or PATCHDATA, and an XForms body under XForms:Model, but also accepts these names from the query string, a form field or a multipart part, so an application cannot tell a client-sent value from the real body.  A cross-site HTML form can post POSTDATA={\"admin\":true} to an endpoint that reads JSON from param('POSTDATA'), a request forgery that needs no CORS preflight.",
