CVE-2025-65112

PubNet is a self-hosted Dart & Flutter package service. Prior to version 1.1.3, the /api/storage/upload endpoint in PubNet allows unauthenticated users to upload packages as any user by providing arbitrary author-id values. This enables identity spoofing, privilege escalation, and supply chain attacks. This issue has been patched in version 1.1.3.

Summary		(es) PubNet es un servicio de paquetes Dart y Flutter autoalojado. Antes de la versión 1.1.3, el endpoint /API/storage/upload en PubNet permite a usuarios no autenticados subir paquetes como cualquier usuario proporcionando valores arbitrarios de author-id. Esto permite la suplantación de identidad, la escalada de privilegios y los ataques a la cadena de suministro. Este problema ha sido parcheado en la versión 1.1.3.
