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."}, {"lang": "es", "value": "Se descubri\u00f3 una vulnerabilidad de denegaci\u00f3n de servicio por expresi\u00f3n regular (ReDoS) en la librer\u00eda Hugging Face Transformers, espec\u00edficamente en la funci\u00f3n `get_configuration_file()` del m\u00f3dulo `transformers.configuration_utils`.
