Intune token disclosure via unskipped tracing argument
Published Aug 1, 2025 · Updated Aug 4, 2025
Sensitive information exposure in Himmelblau 1.0.0 allows local users to read an Intune service access token from the system journal. The tracing instrument on apply_intune_policy omits iwservice_token from its skip list, so debug spans record the token as a function argument. Exploitation requires debug logging, local high-privileged access, and user interaction; the documented consequence is disclosure of Intune compliance status, while further administrative capability remains undocumented.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
