## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-568f-pv23-39p4. This link is maintained to preserve external references.

## Original Description
NLTK versions before 3.10.0 contain a path traversal vulnerability in FramenetCorpusReader and NKJPCorpusReader that allows attackers to parse XML files outside the corpus root by supplying unsafe selectors or poisoned index state. Attackers can exploit frame_by_name, doc, lu, and header methods with crafted parameters to read arbitrary XML files accessible to the application.

## Affected packages

- `nltk <= 3.9.4`

## Remediation

Refer to the advisory for the patched release.
