Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.

Description

Affected of superstatic are vulnerable to path traversal when used on Windows.

Additionally, it is vulnerable to path traversal on other platforms combined with certain Node.js versions which erroneously normalize \\ to / in paths on all platforms (a known example being Node.js v9.9.0).

Recommendation

Update to version 5.0.2 or later.
