      "value": "PySpector is a static analysis security testing (SAST) Framework engineered for modern Python development workflows. The plugin security validator in PySpector uses AST-based static analysis to prevent dangerous code from being loaded as plugins. Prior to version 0.1.8, the blocklist implemented in `PluginSecurity.validate_plugin_code` is incomplete and can be bypassed using several Python constructs that are not checked. An attacker who can supply a plugin file can achieve arbitrary code execution within the PySpector process when that plugin is installed and executed. Version 0.1.8 fixes the issue."

      "value": "PySpector es un framework de pruebas de seguridad de análisis estático (SAST) diseñado para flujos de trabajo de desarrollo de Python modernos. El validador de seguridad de plugins en PySpector utiliza análisis estático basado en AST para evitar que se cargue código peligroso como plugins. Antes de la versión 0.1.8, la lista de bloqueo implementada en ’PluginSecurity.validate_plugin_code’ está incompleta y puede ser eludida utilizando varias construcciones de Python que no se verifican. Un atacante que puede proporcionar un archivo de plugin puede lograr la ejecución de código arbitrario dentro del proceso de PySpector cuando ese plugin se instala y ejecuta. La versión 0.1.8 corrige el problema."
