CVE-2025-23084

Name	CVE-2025-23084
Description	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.
Source	CVE (at NVD; CERT, LWN, oss-sec, fulldisc, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
