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."}], "lastModified": "2026-01-26T15:05:23.427", "sourceIdentifier": "support@hackerone.com"}
