Summary

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-6hwm-xvph-95vm. This link is maintained to preserve external references. ## Original Description NLTK versions before 3.10.3 fail to use validated absolute paths when invoking the Graphviz dot binary in dependencygraph.dot2img and AlignedSent._repr_svg_, allowing attackers to execute arbitrary code by placing a malicious dot binary in the search path or current working directory. Attackers can exploit bare-name binary resolution on Windows via the current working directory or on Unix-like systems via relative PATH entries to execute their binary instead of the legitimate Graphviz tool.

Affected packages

Remediation: No patched version is listed by GitHub.
