Local privilege escalation via undisclosed OLE authorization flaw
Published Jul 14, 2026 · Updated Jul 14, 2026
Improper authorization in Windows OLE across affected Windows releases allows local users to elevate privileges on the system. Microsoft has not disclosed the affected function, authorization decision, or untrusted input that reaches it. Exploitation requires existing low-privilege local access and grants higher privileges, while the public record identifies no remote path or user interaction.
