Vulnerability Title
Untrusted JAR Code Execution in Multiple Stanford Interface Classes in nltk/nltk
Vulnerability Description
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 them via the `java()` function, which invokes `subprocess.Popen()` without integrity verification. This vulnerability is identical to CVE-2026-0848, which was fixed for StanfordSegmenter by adding SHA256 verification. However, the fix was not applied to these additional classes, leaving them susceptible to arbitrary code execution when loading untrusted JAR files.

NLTK 代码注入漏洞
Vulnerability Description
NLTK是NLTK组织开源的一个自然语言工具包。用于支持自然语言处理的研究和开发。 NLTK 3.9.3及之前版本存在代码注入漏洞,该漏洞源于五个Stanford接口类(StanfordPOSTagger、StanfordNERTagger、StanfordParser、StanfordDependencyParser和StanfordNeuralDependencyParser)接受用户可控的JAR路径,并通过java()函数调用subprocess.Popen()执行,未进行完整性验证,可能导致加载不
