CVE-2026-79761 · Severity: medium · CVSS 6.6 · Published 2026-09-24

Termix is a web-based platform for managing SSH connections, terminals, and file transfers to remote servers. An authenticated user can deploy a malicious SSH credential that executes arbitrary commands on a target server with the privileges of the SSH account being configured. This allows an attacker with Termix access to take over remote systems or access sensitive data.

## Technical details

The vulnerability exists in the SSH key deployment flow (src/backend/database/routes/credential-deploy-routes.ts) where a user-controlled public-key token is used to derive a grep pattern that is interpolated into double-quoted shell commands executed on the target host. The grep -F verification paths do not properly escape command substitution or shell metacharacters, allowing authenticated users to break out of the grep context and execute arbitrary commands with the target account's privileges.

## Affected products
