    "title": "Termix: Command injection in SSH key deployment verification",
    "summary": "Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.7.0 until 2.5.1, the Termix SSH key deployment flow derives a grep pattern from a user-controlled public-key token and interpolates it into double-quoted shell commands executed on the selected target host. In src/backend/database/routes/credential-deploy-routes.ts, both grep -F verification paths accept command substitution or quote-breaking shell syntax in keyPattern. An authenticated user who can deploy a crafted SSH credential can therefore execute commands with the selected remote account's privileges. The separate ACME command-injection report is outside this CVE's scope. This issue is fixed in version 2.5.1.",
