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...

DEBIAN-CVE-2026-12252

In nltk/nltk versions 3.9.3 and earlier, five Stanford interface classes StanfordPOSTagger, StanfordNERTagger, StanfordParser, StanfordDependencyParser, and StanfordNeuralDependencyParser are vulnerable to untrusted JAR code execution. These classes accept user-controllable JAR paths and execute...

CVE-2026-12243 Path Traversal via Percent-Encoding in nltk.data.find() and nltk.data.load()

NLTK version 3.9.4 is vulnerable to a path traversal attack due to an incomplete fix for GitHub Issue 3504. The UNSAFENOPROTOCOLRE regex in nltk/data.py checks for literal ../ sequences but fails to account for percent-encoded traversal sequences such as ..%2f. The url2pathname function decodes...

CVE-2026-12243

NLTK 3.9.4 is documented to be vulnerable to a path traversal attack due to an incomplete fix (GitHub Issue #3504). The root cause is that the _UNSAFE_NO_PROTOCOL_RE regex in nltk/data.py only checks for literal ../ sequences and does not account for percent-encoded traversal such as ..%2f. Even ...
