CVE-2025-59464
January 20, 2026
A memory leak in Node.js’s OpenSSL integration occurs when converting "X.509" certificate fields to UTF-8 without freeing the allocated buffer. When applications call "socket.getPeerCertificate(true)", each certificate field leaks memory, allowing remote clients to trigger steady memory growth through repeated TLS connections. Over time this can lead to resource exhaustion and denial of service.
