vite-plugin-static-copy is rollup-plugin-copy for Vite with dev server support. Files not included in src are accessible with a crafted request. The vulnerability is fixed in 2.3.2 and 3.1.2.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
