CVE-2026-79676 NLTK before 3.10.3 Path Traversal via Symlink Bypass

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...

CVE-2026-79676

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...

CVE-2026-79676

NLTK versions before 3.10.3 are affected by a path traversal vulnerability in its corpus readers. The root cause is that these readers reopen root-derived paths using the built-in open() instead of nltk.pathsec.open(), which fails to resolve symlinks confined to a trusted root. An attacker who ca...
