This vulnerability affects versions 4.50.3 and earlier, and is fixed in version 4.52.1. The issue arises from the regex pattern `<s_(.*?)>` which can be exploited to cause excessive CPU consumption through crafted input strings due to catastrophic backtracking. This vulnerability can lead to service disruption, resource exhaustion, and potential API service vulnerabilities, impacting document processing tasks using the Donut model."},{"lang":"es","value":"Se descubrió una vulnerabilidad de denegación de servicio por expresión regular (ReDoS) en la librería Hugging Face Transformers, específicamente en el método `token2json()` de la clase DonutProcessor. Esta vulnerabilidad afecta a las versiones 4.50.3 y anteriores, y se corrigió en la versión 4.52.1. El problema surge del patrón de expresiones regulares ``, que puede explotarse para causar un consumo excesivo de CPU mediante cadenas de entrada manipuladas debido a un retroceso catastrófico. Esta vulnerabilidad puede provocar interrupciones del servicio, agotamiento de recursos y posibles vulnerabilidades del servicio API, lo que afecta las tareas de procesamiento de documentos que utilizan el modelo Donut."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4}],"cvssMetricV30":[{"source":"security@huntr.dev","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4}]},"weaknesses":[{"source":"security@huntr.dev","type":"Secondary","description":[{"lang":"en","value":"CWE-1333"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:huggingface:transformers:*:*:*:*:*:*:*:*","versionEndExcluding":"4.52.1","matchCriteriaId":"603CA36F-1ABE-4950-8FC3-CCB444106044"}]}]}],"references":[{"url":"https://github.com/huggingface/transformers/commit/ebbe9b12dd75b69f92100d684c47f923ee262a93","source":"security@huntr.dev","tags":["Patch"]},{"url":"https://huntr.com/bounties/25282953-5827-4384-bb6f-5790d275721b","source":"security@huntr.dev","tags":["Exploit","Third Party Advisory"]}]}}]}
