GHSA-FG9W-WFP5-J933 NLTK: BllipParser passes caller-supplied model paths to the bllipparser C extension with no pathsec check, enabling arbitrary read

Summary BllipParser in nltk/parse/bllip.py hands caller-supplied filesystem paths to the native bllipparser C extension without routing them through NLTK's pathsec validation. The constructor parameters parsermodel, rerankerfeatures, and rerankerweights, and the alternative fromunifiedmodeldir...

CVE-2026-126295

NLTK from 3.10.0 before 3.10.4 contains an arbitrary file read vulnerability in BllipParser that allows attackers to open files outside NLTK data roots by supplying unvalidated model paths. Attackers controlling parsermodel, rerankerfeatures, rerankerweights, or fromunifiedmodeldir input can make...

CVE-2026-126295

The NLTK library versions 3.10.0 through 3.10.3 are vulnerable to an arbitrary file read vulnerability within the BllipParser component. The root cause is the processing of unvalidated model paths , which allows an attacker to force the bllipparser C extension to read sensitive files outside of t...
