Go to dashboardNode.js 18, 20, 22 and 23 received security releases fixing three flaws: a worker permission bypass through diagnostics_channel (CVE-2025-23083, high), a Windows path traversal via drive names in path.join (CVE-2025-23084, medium), and a memory leak from HTTP/2 GOAWAY frames (CVE-2025-23085, medium). An attacker can escape the Permission Model, read or write files outside intended paths on Windows, or exhaust memory on an HTTP/2 server.

Every team running a Node.js release line 18.x, 20.x, 22.x or 23.x below the fixed versions is affected by the dependency and core fixes. The permission bypass only matters for applications that use the Permission Model (--permission) and the path traversal only for Windows code calling path.join with untrusted input. HTTP/2 memory exhaustion only matters for servers accepting HTTP/2 connections from untrusted peers.

Commercial support for versions past the Maintenance LTS phase is available through our OpenJS Ecosystem Sustainability Program partners Tuesday, January 21, 2025 Security Releases TNJP The Node.js Project Tuesday, January 21, 2025 Security Releases Security releases available Updates are now available for the 23.x, 22.x, 20.x, 18.x Node.js release lines for the following issues. This security release includes the following dependency updates to address public vulnerabilities: undici (v7.2.3, v6.21.1, v5.28.5) on v23.x, v22.x, v20.x, v18.x. Along with the security fixes, the Node.js team has also issued CVEs for End-of-Life (EOL) versions of Node.js. Node.js v17.x or prior CVE-2025-23087 Node.js v19.x CVE-2025-23088 Node.js v21.x CVE-2025-23089 More information in this blog post Worker permission bypass via InternalWorker leak in diagnostics (CVE-2025-23083) - (high) With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker thread is created. This is not limited only to workers but also exposes internal workers, where an instance of them can be fetched, and its constructor can be grabbed and reinstated for malicious usage. This vulnerability affects Permission Model users (--permission) on Node.js v20, v22, and v23. Impact: This vulnerability affects all users in active release lines: 20.x, 22.x, 23.x Thank you, to leodog896 for reporting this vulnerability and thank you RafaelGSS for fixing it. Path traversal by drive name in Windows environment (CVE-2025-23084) - (medium) A vulnerability has been identified in Node.js, specifically affecting the handling of drive names in the Windows environment. Certain Node.js functions do not treat drive names as special on Windows. As a result, although Node.js assumes a relative path, it actually refers to the root directory. On Windows, a path that does not start with the file separator is treated as relative to the current directory. This vulnerability affects Windows users of path.join API. Impact: This vulnerability affects all users in active release lines: 18.x, 20.x, 22.x, 23.x Thank you, to ryotak and taise for reporting this vulnerability and thank you tniessen for fixing it. GOAWAY HTTP/2 frames cause memory leak outside heap (CVE-2025-23085) - (medium) A memory leak could occur when a remote peer abruptly closes the socket without sending a GOAWAY notification. Additionally, if an invalid header was detected by nghttp2, causing the connection to be terminated by the peer, the same leak was triggered. This flaw could lead to increased memory consumption and potential denial of service under certain conditions. This vulnerability affects HTTP/2 Server users on Node.js v18.x, v20.x, v22.x and v23.x. Impact: This vulnerability affects all users in active release lines: 18.x, 20.x, 22.x, 23.x Thank you, to newtmitch for reporting this vulnerability and thank you RafaelGSS for fixing it.
