The vectorizer stores every token from the training data in its `stop_words_` attribute, not only the tokens TF-IDF needs, so tokens meant to be discarded, such as passwords or keys, can be exposed. The impact depends on the data the vectorizer processes.","solution":"Fixed in 1.5.0","labels":["security","privacy"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2024-5206","publishedAt":"2024-06-06T23:16:06.363Z","cveId":"CVE-2024-5206","cweIds":["CWE-921","CWE-922"],"cvssScore":"4.7","cvssSeverity":"medium","severity":"medium","attackType":["pii_leakage"],"issueType":"vulnerability","affectedPackages":["scikit-learn@< 1.5.0 (fixed: 1.5.0)"],"affectedPackageNames":["scikit-learn"],"affectedPackageRefs":["pypi:scikit-learn"],"affectedVendors":[],"affectedVendorsRaw":["scikit-learn","TfidfVectorizer"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"scikit-learn TfidfVectorizer leaks sensitive training tokens via stop_words_","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00189,"epssCheckedAt":"2026-11-04T00:12:27.430Z","kevDateAdded":null,"advisoryAliases":["GHSA-jw8x-6495-233v"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:55:44.350Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2024-05-21T16:33:03.119Z","daysToFix":-16,"fixCheckedAt":"2026-10-29T21:45:46.866Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"scikit-learn","fixedVersion":"1.5.0","matchedVersion":"1.5.0","fixReleasedAt":"2024-05-21T16:33:03.119Z","daysToFix":-16,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:45:46.715Z"}]}}
