Relative Path Traversal vulnerability in Apache Commons VFS before 2.10.0. The FileObject API in Commons VFS has a 'resolveFile' method that takes a 'scope' parameter. Specifying 'NameScope.DESCENDENT' promises that "an exception is thrown if the resolved file is not a descendent of the base file". However, when the path contains encoded ".." characters (for example, "%2E%2E/bar.txt"), it might return file objects that are not a descendent of the base file, without throwing an exception. This issue affects Apache Commons VFS: before 2.10.0. Users are recommended to upgrade to version 2.10.0, which fixes the issue.

    Commons VFS provides a single API for accessing various different file systems. It presents a uniform view     of the files from various different sources, such as the files on local disk, on an HTTP server, or inside     a Zip archive. Some of the features of Commons VFS are:
    * A single consistent API for accessing files of different      types.
    * Support for numerous file system types.
    * Caching of file information. Caches information in-JVM,      and optionally can cache remote file information on the      local file system.
    * Event delivery.
    * Support for logical file systems made up of files from      various different file systems.
    * Utilities for integrating Commons VFS into applications,      such as a VFS-aware ClassLoader and URLStreamHandlerFactory.
    * A set of VFS-enabled Ant tasks.

    Security Fix(es):

    * apache-commons-vfs: Apache Commons VFS: Possible path traversal issue when using NameScope.DESCENDENT     (CVE-2025-27553)
