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 ...

CVE-2026-54293

A flaw was found in NLTK Natural Language Toolkit. The nltk.data.load function is vulnerable to path traversal when processing specially crafted nltk: URLs. An attacker can exploit a decode-after-check flaw, where URL-encoded path separators and traversal segments bypass security checks. This...

CVE-2026-54293

CVE-2026-54293 affects NLTK’s nltk.data.load() in Python. A TOCTOU-style flaw lets an attacker bypass the unsafe-path regex (UNSAFE_NO_PROTOCOL_RE) by using URL-encoded path separators (e.g., %2f, %2e%2e) and then decoding, enabling arbitrary local file reads prior to the fix. Affected until vers...
