Answer in brief
CVE-2024-29180 records a High severity (CVSS 8.3) vulnerability in webpack-dev-middleware before 7.4.6 and 8.3.0 Path Traversal via Non-Slash-Terminated publicPath. The current sources do not mark it as known exploited. The current feed maps webpack/webpack-dev-middleware (generic), webpack/webpack-dev-middleware (generic), zlib/zlib (generic), webpack-dev-middleware (npm) and additional mapped packages. Check affected ranges and fixed versions before updating.

CVSS is 8.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
