Descriptions
TrueLayer.NET is the .Net client for TrueLayer. The vulnerability could potentially allow a malicious actor to gain control over the destination URL of the HttpClient used in the API classes. For applications using the SDK, requests to unexpected resources on local networks or to the internet could be made which could lead to information disclosure. The issue can be mitigated by having strict egress rules limiting the destinations to which requests can be made, and applying strict validation to any user input passed to the `truelayer-dotnet` library. Versions of TrueLayer.Client `v1.6.0` and later are not affected.

Para las aplicaciones que utilizan el SDK, se podrían realizar solicitudes a recursos inesperados en redes locales o a Internet, lo que podría dar lugar a la divulgación de información. El problema se puede mitigar teniendo reglas de salida estrictas que limiten los destinos a los que se pueden realizar las solicitudes y aplicando una validación estricta a cualquier entrada del usuario pasada a la librería "truelayer-dotnet". Las versiones de TrueLayer.Client `v1.6.0` y posteriores no se ven afectadas.
