A later anonymous form submission associates that temporary attachment with the newly created submission. When an administrator opens the submission, the component's JavaScript retrieves the stored attachment record and concatenates `file.name` directly into an HTML string. The complete string is assigned to `innerHTML`.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://www.balbooa.com/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
