Summary
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the str_eval() function in notification_handler.py implements a sandboxed eval() for notification text templates. The sandbox attempts to restrict callable names by inspecting code.co_names of the compiled code object. However, co_names only contains names from the outer code object. When a lambda expression is used, it creates a nested code object whose attribute accesses are stored in code.co_consts, NOT in code.co_names. The sandbox never inspects nested code objects. This issue has been patched in version 2.17.0.

"value": "Tautulli es una herramienta de monitoreo y seguimiento basada en Python para Plex Media Servidor. Antes de la versi\u00f3n 2.17.0, la funci\u00f3n str_eval() en notification_handler.py implementa un eval() en sandbox para plantillas de texto de notificaci\u00f3n. El sandbox intenta restringir los nombres invocables inspeccionando code.co_names del objeto de c\u00f3digo compilado. Sin embargo, co_names solo contiene nombres del objeto de c\u00f3digo externo. Cuando se utiliza una expresi\u00f3n lambda, esta crea un objeto de c\u00f3digo anidado cuyos accesos a atributos se almacenan en code.co_consts, NO en code.co_names. El sandbox nunca inspecciona objetos de c\u00f3digo anidados. Este problema ha sido parcheado en la versi\u00f3n 2.17.0."
