Local privilege escalation via undisclosed access control
Published Oct 14, 2025 · Updated Oct 14, 2025
Improper access control in Microsoft Visual Studio 2017, 2019, and 2022 allows local users to elevate privileges on Windows. Microsoft has not disclosed the affected component or the incorrect access-control operation performed on attacker-influenced input. Exploitation requires low privileges and user interaction, after which the attacker gains elevated local privileges over the affected system.
