CVE-2026-45748
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTermix 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. Version 2.3.2 patches the issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceTermix versions prior to 2.3.2 contain a critical OS command injection vulnerability in the POST /ssh/tunnel/connect endpoint. The application directly interpolates user-supplied fields (endpointIP, endpointUsername, password) into an SSH tunnel command without proper escaping or sanitization, allowing an attacker to inject arbitrary shell commands that execute on the source SSH host.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Termix versionRun 'termix --version' or check the application package metadata to determine the installed version numberAffected if The version is 2.1.0 or higher but lower than 2.3.2
-
Verify SSH tunnel feature is enabledCheck Termix configuration files or settings for the SSH tunnel module statusAffected if The SSH tunnel feature is enabled and accessible to users
-
Confirm web/API interface is accessibleInspect whether the Termix web interface or API service is running and reachableAffected if The POST /ssh/tunnel/connect endpoint is exposed and accepts requests
If Termix version is between 2.1.0 and 2.3.1 inclusive AND the SSH tunnel feature is enabled, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.3.2
Upgrade to Termix version 2.3.2 or later, which implements proper input sanitization and escaping for shell command construction.
Upgrade to Termix version 2.3.2
- 1. Back up the Termix application data and configuration files before upgrading
- 2. Stop the Termix service if it is currently running
- 3. Upgrade Termix to version 2.3.2 or later using your package manager or deployment method (e.g., pip install termix==2.3.2, docker pull termix:2.3.2, or your system's package manager)
- 4. Verify the upgrade was successful by checking the installed version (e.g., termix --version)
- 5. Restart the Termix service
- 6. Test the POST /ssh/tunnel/connect endpoint to confirm the command injection vulnerability is patched
