This requires the site owner to have added a request-derived tag to the form content and to embed the form with the block rather than the classic shortcode.","cvssScore":4.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://wpscan.com/vulnerability/a8b2a564-25ae-4ed8-9c2c-989b104ba4c8/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
