Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Commons VFS (org.apache.commons:commons-vfs2) before 2.10.0 is vulnerable to relative path traversal. When a caller uses the resolveFile method with NameScope.DESCENDENT and the path contains percent-encoded ".." sequences, the method can return file objects outside the base file without throwing an exception. The source does not describe the attacker's required access. Upgrade to commons-vfs2 version 2.10.0 or later.
