A critical vulnerability, tracked as CVE-2025-55241, has been identified within Microsoft Entra ID, previously known as Azure Active Directory, allowing attackers to potentially assume global administrative control across all Microsoft tenants using a single compromised Actor token. Discovered by security researcher Dirk-Jan Mollema, this flaw stems from a validation error that fails to ensure tenant boundaries, enabling an attacker with access to a low-privilege token from a test environment to read sensitive user profiles, create new Global Admin accounts, and hijack existing ones without triggering any alerts. The implications of this issue highlight significant weaknesses in centralized identity management systems, as it exposes multinational corporations and small businesses alike to severe risks of data breaches and unauthorized access. As this incident reflects broader vulnerabilities in trusted platforms, it underscores the urgent need for organizations to consider adopting decentralized identity frameworks that can mitigate such risks by eliminating single points of trust and enhancing security against potential exploitation.
