Regular expressions in the SubWordJapaneseTokenizer class process specially crafted inputs, and a regex with exponential complexity causes excessive backtracking. The affected version is v4.48.1 (latest), and the result is high CPU usage and potential application downtime.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-1194","publishedAt":"2025-04-29T16:15:31.717Z","cveId":"CVE-2025-1194","cweIds":["CWE-1333"],"cvssScore":"6.5","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["transformers@< 4.50.0 (fixed: 4.50.0)"],"affectedPackageNames":["transformers"],"affectedPackageRefs":["pypi:transformers"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["huggingface/transformers","GPT-NeoX-Japanese"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"huggingface/transformers ReDoS in GPT-NeoX-Japanese tokenizer via crafted input","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00492,"epssCheckedAt":"2026-11-04T12:08:35.257Z","kevDateAdded":null,"advisoryAliases":["GHSA-fpwr-67px-3qhx"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:53:55.008Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2025-03-21T13:40:18.450Z","daysToFix":-39,"fixCheckedAt":"2026-10-29T21:44:37.659Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"framework","llmSpecific":true,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"transformers","fixedVersion":"4.50.0","matchedVersion":"4.50.0","fixReleasedAt":"2025-03-21T13:40:18.450Z","daysToFix":-39,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:44:37.508Z"}]}}
