The image optimization endpoint (`/_next/image`) loads external images entirely into memory without enforcing a maximum size limit, allowing an attacker to cause out-of-memory conditions by requesting optimization of arbitrarily large images. This vulnerability requires that `remotePatterns` is configured to allow image optimization from external domains and that the attacker can serve or control a large image on an allowed domain.\r\n\r\nStrongly consider upgrading to 15.5.10 or 16.1.5 to reduce risk and prevent availability issues in Next applications."}], "lastModified": "2026-01-27T15:15:56.453", "sourceIdentifier": "support@hackerone.com"}
