Aliases CVE-2017-16654
Summary An attacker can navigate to arbitrary directories via the dot-dot-slash attack This package includes various bundle readers that are used to read resource bundles from the local filesystem. The `read()` methods of these classes use a path and a locale to determine the language bundle to retrieve. The locale argument value is commonly retrieved from untrusted user input (like a `URL` parameter). An attacker can use this argument to navigate to arbitrary directories via the dot-dot-slash attack.
