The vulnerability is due to inefficient regular expression complexity in the `SETTING_RE` variable within the `transformers/commands/chat.py` file. The regex contains repetition groups and non-optimized quantifiers, leading to exponential backtracking when processing 'almost matching' payloads. This can degrade application performance and potentially result in a denial-of-service (DoS) when handling specially crafted input strings. The issue is fixed in version 4.51.0."},{"lang":"es","value":"Se descubrió una vulnerabilidad de denegación de servicio por expresión regular (ReDoS) en el repositorio huggingface/transformers, concretamente en la versión 4.49.0. La vulnerabilidad se debe a la complejidad ineficiente de la expresión regular en la variable `SETTING_RE` del archivo `transformers/commands/chat.py`. La expresión regular contiene grupos de repetición y cuantificadores no optimizados, lo que provoca un retroceso exponencial al procesar payloads casi coincidentes. Esto puede reducir el rendimiento de la aplicación y potencialmente provocar una denegación de servicio (DoS) al procesar cadenas de entrada especialmente manipuladas.
