This link is maintained to preserve external references.\n\n## Original Description\nNLTK 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.\n\n## Affected packages\n\n- `nltk <= 3.9.4`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"twilight","depthScore":32,"depthScoreParts":{"impact":32.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
