The vulnerability arises from the unexpected storage of all tokens present in the training data within the `stop_words_` attribute, rather than only storing the subset of tokens required for the TF-IDF technique to function. This behavior leads to the potential leakage of sensitive information, as the `stop_words_` attribute could contain tokens that were meant to be discarded and not stored, such as passwords or keys. The impact of this vulnerability varies based on the nature of the data being processed by the vectorizer."}, {"lang": "es", "value": "Se identific\u00f3 una vulnerabilidad de fuga de datos confidenciales en TfidfVectorizer de scikit-learn, espec\u00edficamente en versiones hasta la 1.4.1.post1 incluida, que se solucion\u00f3 en la versi\u00f3n 1.5.0. La vulnerabilidad surge del almacenamiento inesperado de todos los tokens presentes en los datos de entrenamiento dentro del atributo `stop_words_`, en lugar de almacenar solo el subconjunto de tokens necesarios para que funcione la t\u00e9cnica TF-IDF.
