Summary

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-p4rw-rvv2-7xwr. This link is maintained to preserve external references. ## Original Description NLTK versions before 3.10.3 contain a path traversal vulnerability in corpus readers that reopen root-derived paths using built-in open() instead of nltk.pathsec.open(), allowing symlinks to escape trusted roots. Attackers who stage symlinked corpus files under a trusted data root can disclose outside-root content through normal corpus reader methods like channels(), domains(), and synonyms().

Affected packages

Remediation: No patched version is listed by GitHub.
