CVE-2026-45748 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. The `POST /ssh/tunnel/connect` endpoint in Termix prior to version 2.3.2 builds an SSH tunnel command by interpolating user-controlled host record fields (`endpointIP`, `endpointUsername`, `password`) directly into a shell command without escaping, allowing persistent OS command injection on the source SSH host. EPSS estimates a 1.73% chance of exploitation in the next 30 days.
