CVE-2026-24902: Adguard Trusttunnel

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Adguard Trusttunnel: before 0.9.114 (fixed in 0.9.114)
