Prior to 0.8.18, an attacker who can send an HTTP request to a server running the LangSmith SDK's TracingMiddleware can cause that server to read an arbitrary file from its local filesystem and upload the contents to LangSmith as a trace attachment. Depending on how the distributed trace system is deployed, triggering a read may not require authentication. Retrieving the contents requires read access to the LangSmith workspace the traces are sent to. The net effect is a trust-boundary crossing: a party with workspace trace-read access (for example a low-privilege workspace member, a contractor, or a compromised teammate account) gains the ability to read files from any server running TracingMiddleware, a capability outside that workspace's intended trust boundary. This vulnerability is fixed in 0.8.18."}, {"lang": "es", "value": "Los SDK de cliente de LangSmith proporcionan SDK para interactuar con la plataforma LangSmith. Antes de la versi\u00f3n 0.8.18, un atacante que puede enviar una solicitud HTTP a un servidor que ejecuta el TracingMiddleware del SDK de LangSmith puede hacer que ese servidor lea un archivo arbitrario de su sistema de archivos local y cargue el contenido a LangSmith como un archivo adjunto de traza. Dependiendo de c\u00f3mo se implemente el sistema de trazas distribuidas, activar una lectura puede no requerir autenticaci\u00f3n. La recuperaci\u00f3n del contenido requiere acceso de lectura al espacio de trabajo de LangSmith al que se env\u00edan las trazas. El efecto neto es un cruce de l\u00edmite de confianza: una parte con acceso de lectura de trazas del espacio de trabajo (por ejemplo, un miembro del espacio de trabajo con privilegios bajos, un contratista o una cuenta de compa\u00f1ero de equipo comprometida) obtiene la capacidad de leer archivos de cualquier servidor que ejecuta TracingMiddleware, una capacidad fuera del l\u00edmite de confianza previsto de ese espacio de trabajo.
