      "value": "ACE vulnerability in conditional configuration file processing  by QOS.CH logback-core up to and including version 1.5.36 in Java applications, allows an attacker to execute arbitrary code circumventing existing protections against CVE-2025-11226 by compromising an existing logback configuration file or by injecting an environment variable before program execution.\n\n\n\nA successful attack requires the presence of Janino library to be present on the user's class path. In addition, the attacker must  have write access to a \nconfiguration file. Alternatively, the attacker could inject a malicious \nenvironment variable pointing to a malicious configuration file. In both \ncases, the attack requires existing privilege.\n\nPlease note that in logack version 1.5.37 conditional processing using Janino was removed."

      "value": "Una vulnerabilidad ACE en el procesamiento condicional de archivos de configuración por QOS.CH logback-core hasta e incluyendo la versión 1.5.36 en aplicaciones Java, permite a un atacante ejecutar código arbitrario eludiendo las protecciones existentes contra CVE-2025-11226 al comprometer un archivo de configuración de logback existente o al inyectar una variable de entorno antes de la ejecución del programa.\n\nUn ataque exitoso requiere que la biblioteca Janino esté presente en la ruta de clases del usuario. Además, el atacante debe tener acceso de escritura a un archivo de configuración. Alternativamente, el atacante podría inyectar una variable de entorno maliciosa que apunte a un archivo de configuración malicioso. En ambos casos, el ataque requiere privilegios existentes.\n\nTenga en cuenta que en la versión 1.5.37 de logack se eliminó el procesamiento condicional usando Janino."
