CVE-2026-73298
NVD analysis in progress
The Microsoft Container Migration Solution Accelerator is a multi-service application that provides a multi-agent, AI-driven migration solution for moving container service configurations to Azure Kubernetes Service. In version 2.1.2 and earlier, a security vulnerability was identified in the Container Migration Solution Accelerator, specifically an authenticated IDOR (Insecure Direct Object Reference) that allows users to read, write, and delete processes belonging to other authenticated users. The issue affects multiple API endpoints, where ownership checks are missing, enabling unauthorized access and modification of migration data across users within the same organization. The vulnerability is present in both process and file management APIs, and the application relies on Entra ID authentication but lacks proper authorization controls between users. Authenticated users are able to access, modify, and delete processes and files belonging to other users without proper authorization checks.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Changing an identifier in the request grants access to another user’s data.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
