AI description
CVE-2026-47301 is an improper access control vulnerability found in Microsoft Configuration Manager (SCCM), specifically within the AdminService REST API. This flaw stems from a missing role-based access control (RBAC) check, which allows an authenticated domain user to submit a malicious CAB archive without possessing the necessary SCCM administrative roles. This vulnerability is a component of a larger, multi-step remote code execution (RCE) attack chain. While Microsoft has released a patch addressing CVE-2026-47301, other elements of the complete RCE chain, such as path traversal and weak code-signing validation, are expected to be fully resolved in later updates.
