CVE-2025-9474Public exploit

Traffic interception via world-writable proxy socket

Published Aug 26, 2025 · Updated Sep 5, 2025

Insecure socket permissions in Clash Party 1.8.0 and 1.8.1 on macOS allow local users to alter system-wide proxy settings. The enableSysProxy handler uses the root-owned /tmp/mihomo-party-helper.sock UNIX socket with mode 0666 and accepts unauthenticated HTTP proxy-configuration requests. A low-privileged local account that reaches the socket can redirect host traffic through an attacker-controlled proxy, enabling interception and data disclosure.
