AI-suggested
A patch is available in version 1.0.8_14. Users should upgrade affected NLTK versions to 1.0.8_14 or later to remediate this vulnerability. No additional mitigation steps are indicated by the vendor advisory.
Description
NLTK versions up to and including 3.9.2 contain a path traversal vulnerability in multiple CorpusReader classes, allowing attackers to read arbitrary files on the server. This flaw arises from improper sanitization of file paths in classes such as WordListCorpusReader, TaggedCorpusReader, and BracketParseCorpusReader. Exploitation can lead to unauthorized access to sensitive files, including system files and private keys, and may enable remote code execution when combined with other vulnerabilities. A fix is available in version 1.0.8_14.
