9.8 CRITICALpublic exploit availablePublished 2026-08-05 · Updated 2026-08-10
AI risk analysis
- Summary
- The IoTSharp BlobStorageController.cs lacks proper authorization, allowing unauthenticated attackers to manipulate storage endpoints, leading to potential data breaches and unauthorized access.
- Exploitability
- Exploitation is relatively straightforward as no authentication is required, and the endpoints are publicly accessible.
- Blast radius
- If exploited, this could result in significant data loss or corruption, impacting the integrity and confidentiality of the IoTSharp system.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Apply the [Authorize] attribute to the BlobStorageController.cs endpoints or configure a global authorization FallbackPolicy in Startup.cs.

NVD description
IoTSharp BlobStorageController.cs lacks the [Authorize] attribute applied to every other controller in the application (DevicesController, CustomersController, TenantsController, etc.), and no global authorization FallbackPolicy is configured in Startup.cs, leaving its Upload/Download/List/Modify/Delete endpoints reachable by unauthenticated remote attackers.
