Microsoft Graph
Monthly
Microsoft Graph exposes sensitive information to authenticated network attackers through an information disclosure flaw classified under CWE-200. Any attacker holding a valid low-privilege credential can query the Microsoft Graph API over the network to retrieve data they should not have access to, without requiring additional user interaction or elevated rights. No active exploitation is confirmed (not in CISA KEV), and Microsoft has released an official fix; however, the high confidentiality impact and low attack complexity make this a meaningful risk for any organization relying on Microsoft 365 services.
Microsoft Graph exposes sensitive data to authenticated network attackers due to improper authorization controls, allowing low-privileged API callers to retrieve information beyond their granted scope. The vulnerability (CVSS 6.5) carries high confidentiality impact (C:H) with no integrity or availability consequence, making it a pure data disclosure risk against Microsoft's unified cloud API surface. No public exploit code has been identified at time of analysis, and Microsoft has released a server-side patch via MSRC advisory CVE-2026-47655.
