CVE-2026-65795

Privilege escalation via relative path traversal

Published Aug 11, 2026 · Updated Aug 25, 2026

Relative path traversal in Windows DNS allows local users to elevate privileges through crafted path input on affected Windows systems. Microsoft identifies relative path traversal in Windows DNS but has not disclosed the affected function, path source, or privileged operation. The attacker must already hold high local privileges; the vendor describes the result only as elevation of privilege.
