H Directory Traversal rollup is a Next-generation ES module bundler Affected versions of this package are vulnerable to Directory Traversal in the `Bundle` class in `bundle.ts`, which handles file name sanitization in the core engine. An attacker can overwrite arbitrary files on the host filesystem outside the application root by supplying malicious output filenames containing traversal sequences through CLI named inputs, manual chunk aliases, or malicious plugins. This can allow further attacks in which critical system or user configuration files are read and executed in unintended ways. How to fix Directory Traversal?
