Synopsis

Node.js - JavaScript run-time environment is affected by multiple vulnerabilities.

Description

The version of Node.js installed on the remote host is prior to 22.23.0, 24.17.0, or 26.3.1. It is, therefore, affected by multiple vulnerabilities as referenced in the Thursday, June 18, 2026 Security Releases advisory.

- A flaw in Node.js WebCrypto implementation can crash the process if the input of subtle.encrypt() is a multiple of 2GiB. (CVE-2026-48933)

- A flaw in Node.js TLS hostname handling can cause Node.js unicode dot separator handling can lead to tls wildcard-depth authentication bypass due to resolver and verifier hostname normalization mismatch.
(CVE-2026-48618)

- A flaw in Node.js proxy tunnel error handling could expose proxy credentials in ERR_PROXY_TUNNEL error messages. When proxy credentials are embedded in the proxy URL, they may be exposed through error handling paths and captured by logs, diagnostics, or other error consumers. (CVE-2026-48615)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Node.js version 22.23.0 / 24.17.0 / 26.3.1 or later.
