CVE-2026-48615

A flaw was found in Node.js. When proxy credentials are embedded in a proxy URL, an issue in the proxy tunnel error handling can lead to the exposure of these credentials. This information disclosure vulnerability allows an attacker to potentially capture sensitive proxy credentials through logs, diagnostics, or other error-consuming mechanisms.

CVE-2026-48618

A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS (Transport Layer Security) hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security boundaries, potentially leading to unauthorized access and confidentiality impact.

CVE-2026-48933

A flaw was found in the Node.js WebCrypto implementation. A remote attacker could exploit this vulnerability by providing an input to the `subtle.encrypt()` function that is a multiple of 2 gigabytes (GiB). This could lead to a denial of service (DoS) by crashing the Node.js process.
