CVE-2026-79676 is fixed in nltk on 1 platform by DEBIAN-CVE-2026-79676 (version 3.10.3-1), released August 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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().
