From 2.12.0 until 2.14.2, NestedSecretsSettingsSource reads secret values from files in a configured secrets_dir. When secrets_nested_subdir=True, a directory entry inside secrets_dir that is a symbolic link pointing outside secrets_dir is followed, so files outside the configured directory are read into settings values. The same code path bypasses the documented secrets_dir_max_size protection. An attacker or lower-privileged component able to influence entries in the configured secrets directory (for example, a writable or shared secrets mount) can turn this into an unintended local file read into settings and can defeat the advertised loading-size cap. This vulnerability is fixed in 2.14.2."}, {"lang": "es", "value": "pydantic-settings proporciona gesti\u00f3n de configuraciones utilizando Pydantic. Desde 2.12.0 hasta 2.14.2, NestedSecretsSettingsSource lee valores secretos de archivos en un secrets_dir configurado. Cuando secrets_nested_subdir=True, se sigue una entrada de directorio dentro de secrets_dir que es un enlace simb\u00f3lico que apunta fuera de secrets_dir, por lo que los archivos fuera del directorio configurado se leen como valores de configuraci\u00f3n.

Un atacante o un componente con privilegios inferiores capaz de influir en las entradas del directorio de secretos configurado (por ejemplo, un montaje de secretos escribible o compartido) puede convertir esto en una lectura de archivo local no intencionada en la configuraci\u00f3n y puede anular el l\u00edmite de tama\u00f1o de carga anunciado.
