CVE-2026-24902

TrustTunnel has SSRF and private network restriction bypass via numeric address destinations

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 allowprivatenetwork_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 isglobalip, is_loopback), allowing loopback/private targets to be reached by supplying a numeric IP. The vulnerability is fixed in version 0.9.114.
