Summary

A security flaw was discovered in farion1231 cc-switch up to version 3.12.3 in the ProxyServer component (file src-tauri/src/proxy/server.rs). Manipulation leads to a permissive cross-domain policy with untrusted domains. The exploit has been publicly released and can be used for remote attacks.

Risk Assessment

A permissive cross-domain policy may allow attackers to bypass browser security and access data or functions in the application context. This could lead to information leakage or unauthorized actions.

Recommendation

Update cc-switch to a version newer than 3.12.3 that fixes the vulnerability. Until then, limit exposure of ProxyServer and monitor for unusual cross-origin requests.
