CVE-2024-5206
MEDIUMDescription
A sensitive data leakage vulnerability was identified in scikit-learn's TfidfVectorizer, specifically in versions up to and including 1.4.1.post1, which was fixed in version 1.5.0. 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.

Common questions
How do I fix CVE-2024-5206?
Upgrade scikit-learn to 1.5.0 or later.
Is CVE-2024-5206 being actively exploited?
Not that we know of. CVE-2024-5206 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.19% is the estimated probability that it will be exploited in the next 30 days. That is higher than 9% of all scored CVEs.
How severe is CVE-2024-5206?
CVE-2024-5206 has a CVSS v3 base score of 4.7, rated medium. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
What does CVE-2024-5206 affect?
Published advisories record a fix for scikit-learn (NVD). Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
