Local code execution via undisclosed type confusion
Published Jul 8, 2025 · Updated Feb 13, 2026
Type confusion in Microsoft Office allows attackers to execute code locally after a user performs an unspecified action. Microsoft has not disclosed the affected component, incompatible resource type, or operation that reaches the type confusion. Exploitation requires user interaction but no prior privileges, and successful exploitation runs attacker-controlled code in the user's context.
