Description from the CVE record (CVE.org), as published by its numbering authority
webpack-dev-middleware 5.3.4, 6.1.2 through 6.1.3, 7.1.0 before 7.4.6, and 8.0.0 before 8.3.0 contains a path traversal vulnerability in getFilenameFromUrl that bypasses the fix for CVE-2024-29180: a publicPath without a trailing slash is matched by string prefix, and the '..' guard runs before that prefix is stripped. Unauthenticated attackers can request a path such as /assets../secret to read files one directory above the output directory when the middleware serves from the physical filesystem through writeToDisk or a custom outputFileSystem.
