How CVE-2025-29814 Works
CVE-2025-29814 is an improper authorization flaw in Microsoft Partner Center that enables authenticated attackers to escalate privileges via network-based exploitation. The vulnerability arises when role-based access controls (RBAC) fail to properly validate user permissions, allowing an attacker with low-level access to manipulate API requests and gain administrative rights. Attackers exploit this by crafting malicious API calls that bypass authorization checks, leading to unauthorized access to sensitive functions or data.
