NLTK: FileSystemPathPointer.open() sandbox check is dead code — arbitrary file read via file:// protocol

Summary There's a logic bug in FileSystemPathPointer.open inside nltk/data.py that makes the sandbox check permanently inert. The guard condition is always False — meaning any file the process can read is accessible by passing a file:// URL to nltk.data.load. --- Details In nltk/data.py,...
