Severity ?
5.3 (Medium) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Summary
A Regular Expression Denial of Service (ReDoS) vulnerability was discovered in the Hugging Face Transformers library, specifically in the `get_configuration_file()` function within the `transformers.configuration_utils` module. The affected version is 4.49.0, and the issue is resolved in version 4.51.0. The vulnerability arises from the use of a regular expression pattern `config\.(.*)\.json` that can be exploited to cause excessive CPU consumption through crafted input strings, leading to catastrophic backtracking. This can result in model serving disruption, resource exhaustion, and increased latency in applications using the library.

La versi\u00f3n afectada es la 4.49.0 y el problema se solucion\u00f3 en la versi\u00f3n 4.51.0. La vulnerabilidad surge del uso de un patr\u00f3n de expresi\u00f3n regular `config\\.(.*)\\.json`, que puede explotarse para causar un consumo excesivo de CPU mediante cadenas de entrada manipuladas, lo que provoca un retroceso catastr\u00f3fico. Esto puede provocar interrupciones en el servicio del modelo, agotamiento de recursos y mayor latencia en las aplicaciones que utilizan la librer\u00eda."
