Technical details

This vulnerability (CVE-2026-76137) is a missing authentication flaw (CWE-306) in VOCALOID6 Editor versions 6.13.1 and earlier. The application exposes a local named pipe without proper authentication controls, allowing any process running under the same local user account to interact with it. An attacker can exploit this via the named pipe to escalate privileges or perform unauthorized operations. This requires local access and the VOCALOID6 Editor to be running; privilege escalation is possible without requiring elevated privileges initially. Yamaha released version 6.13.3 (September 16, 2026) to address this issue.
