Summary
Duplicate Advisory: JVM argument injection bypass via per-call options in the NLTK Stanford wrappers (incomplete fix of CVE-2026-12841)
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-m4rf-3fr8-xwx3. This link is maintained to preserve external references.

Original Description

NLTK before 3.10.3 fails to validate JVM options passed through the per-call options parameter in the java() function, allowing attackers to inject dangerous JVM flags. Attackers can supply malicious options like -agentpath, -javaagent, or @argfile to Stanford wrapper classes to achieve arbitrary code execution.
