      "value": "A Regular Expression Denial of Service (ReDoS) vulnerability exists in the latest version of gaizhenbiao/chuanhuchatgpt. The vulnerability is located in the filter_history function within the utils.py module. This function takes a user-provided keyword and attempts to match it against chat history filenames using a regular expression search. Due to the lack of sanitization or validation of the keyword parameter, an attacker can inject a specially crafted regular expression, leading to a denial of service condition. This can cause severe degradation of service performance and potential system unavailability."

      "value": "Existe una vulnerabilidad de denegaci\u00f3n de servicio de expresi\u00f3n regular (ReDoS) en la \u00faltima versi\u00f3n de gaizhenbiao/chuanhuchatgpt. La vulnerabilidad se encuentra en la funci\u00f3n filter_history dentro del m\u00f3dulo utils.py. Esta funci\u00f3n toma una palabra clave proporcionada por el usuario e intenta compararla con los nombres de archivos del historial de chat mediante una b\u00fasqueda de expresi\u00f3n regular. Debido a la falta de sanitizaci\u00f3n o validaci\u00f3n del par\u00e1metro de palabra clave, un atacante puede inyectar una expresi\u00f3n regular especialmente manipulada, lo que lleva a una condici\u00f3n de denegaci\u00f3n de servicio. Esto puede provocar una degradaci\u00f3n grave del rendimiento del servicio y una posible indisponibilidad del sistema."
