github.com/dnscrypt/dnscrypt-proxy is vulnerable to Privilege escalation. The vulnerability is caused by insecure file permissions on the dnscrypt-proxy executable, which allows non-privileged users to overwrite it with malicious code, leading to potential privilege escalation to root when the modified binary is executed.
