      "title": "A flaw in Node.js HTTP request handling causes an uncaught \u0060TypeError\u0060 when a request is received with a header named \u0060__proto__\u0060 and the application accesses \u0060req.headersDistinct\u0060.\n\nWhen this occurs, \u0060dest[\u0022__proto__\u0022]\u0060 resolves to \u0060Object.prototype\u0060 rather than \u0060undefined\u0060, causing \u0060.push()\u0060 to be called on a non-array. This exception is thrown synchronously inside a property getter and cannot be intercepted by \u0060error\u0060 event listeners, meaning it cannot be handled without wrapping every \u0060req.headersDistinct\u0060 access in a \u0060try/catch\u0060.\n\n* This vulnerability affects all Node.js HTTP servers on **20.x, 22.x, 24.x, and v25.x**",
