CVE-2026-69805Network attack vector

Privilege escalation via dump-controlled remote paths

Published Sep 8, 2026 · Updated Sep 9, 2026

Path-control flaws in Microsoft Visual Studio 2022 before 17.14.40 allow remote attackers to elevate privileges through crafted dump files. Microsoft.Diagnostics.Runtime trusts remote paths embedded in dump metadata, allowing NTLMv2 credential disclosure or loading of attacker-controlled native code. Exploitation requires user interaction with a crafted dump or memory snapshot, and Microsoft rates attack complexity as high.
