CVE-2025-71408
NLTK Natural Language Toolkit before version 3.9.3 contains an eval injection vulnerability in the nltk.collocations module that allows an attacker who controls command-line arguments to execute arbitrary Python code. When collocations.py is invoked directly, the main block passes command-line...
CVE-2025-71408 NLTK < 3.9.3 Eval Injection via collocations.py Command-Line Arguments
NLTK Natural Language Toolkit before version 3.9.3 contains an eval injection vulnerability in the nltk.collocations module that allows an attacker who controls command-line arguments to execute arbitrary Python code. When collocations.py is invoked directly, the main block passes command-line...
CVE-2025-71408
The CVE-2025-71408 issue affects NLTK up to version 3.9.2 (pre-3.9.3). The vulnerability lies in nltk.collocations’ main path, where command‑line arguments are passed directly to eval() to form BigramAssocMeasures suffixes without a allowlist or sanitization, enabling an attacker who can control ...

PYSEC-2026-1556 llama-index has Insecure Temporary File
The llamaindex library version 0.12.33 sets the NLTK data directory to a subdirectory of the codebase by default, which is world-writable in multi-user environments. This configuration allows local users to overwrite, delete, or corrupt NLTK data files, leading to potential denial of service, dat...
CVE-2026-12252
A flaw was found in the nltk library. Several Stanford interface classes within nltk are susceptible to arbitrary code execution. This vulnerability allows a local attacker to execute malicious code by providing an untrusted Java Archive JAR file, as the system lacks integrity verification for...
