Summary

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-72r2-7mfr-5xr9. This link is maintained to preserve external references. ## Original Description NLTK versions before 3.10.0 contain a logic bug in FileSystemPathPointer.open() where the sandbox validation check compares a normalized path against itself, making the security check permanently inert. Attackers can pass file:// URLs to nltk.data.load() to read arbitrary files accessible to the process user, including credentials and configuration files.
