CVE-2023-31747Public exploit

Local privilege escalation via unquoted service path

Published May 23, 2023 · Updated Jul 9, 2026

Local privilege escalation in Wondershare Filmora 12 build 12.2.1.2088 allows local users to execute code with SYSTEM privileges. The NativePushService registers an unquoted executable path containing spaces and runs automatically as LocalSystem from a directory writable by ordinary users. A local user who can place a crafted executable in an earlier path segment gains local administrative control when the service starts.
