This function, responsible for converting TensorFlow weight names to PyTorch format, uses a regex pattern `/[^/]*___([^/]*)/` that can be exploited to cause excessive CPU consumption through crafted input strings due to catastrophic backtracking. The vulnerability affects versions up to 4.51.3 and is fixed in version 4.53.0. This issue can lead to service disruption, resource exhaustion, and potential API service vulnerabilities, impacting model conversion processes between TensorFlow and PyTorch formats."}, {"lang": "es", "value": "Existe una vulnerabilidad de denegaci\u00f3n de servicio de expresiones regulares (ReDoS) en la librer\u00eda Hugging Face Transformers, espec\u00edficamente en la funci\u00f3n `convert_tf_weight_name_to_pt_weight_name()`. Esta funci\u00f3n, responsable de convertir los nombres de peso de TensorFlow al formato de PyTorch, utiliza un patr\u00f3n de expresiones regulares `/[^/]*___([^/]*)/` que puede explotarse para causar un consumo excesivo de CPU mediante cadenas de entrada manipuladas debido a un retroceso catastr\u00f3fico. La vulnerabilidad afecta a las versiones hasta la 4.51.3 y se corrigi\u00f3 en la versi\u00f3n 4.53.0.
