CVE-2026-24902
January 29, 2026
TrustTunnel is an open-source VPN protocol with a server-side request forgery and and private network restriction bypass in versions prior to 0.9.114. In "tcp_forwarder.rs", SSRF protection for "allow_private_network_connections = false" was only applied in the "TcpDestination::HostName(peer)" path. The "TcpDestination::Address(peer) => peer" path proceeded to "TcpStream::connect()" without equivalent checks (for example "is_global_ip", "is_loopback"), allowing loopback/private targets to be reached by supplying a numeric IP. The vulnerability is fixed in version 0.9.114.
