CVE-2025-43012
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 · uneditedIn JetBrains Toolbox App before 2.6 command injection in SSH plugin was possible
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 confidenceA command injection vulnerability exists in the SSH plugin of JetBrains Toolbox App versions prior to 2.6. The vulnerability allows attackers to execute arbitrary commands on the target system through the SSH functionality, likely due to insufficient input validation when handling SSH connection parameters or commands.

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.
-
Locate JetBrains Toolbox installationSearch for the JetBrains Toolbox executable (toolbox.exe on Windows, JetBrains Toolbox on macOS/Linux) in common installation directories such as %LOCALAPPDATA%\JetBrains\Toolbox on Windows, /Applications on macOS, or ~/.local/share/JetBrains/Toolbox on Linux. Also check if installed via snap, flatpak, or other package managers.Affected if JetBrains Toolbox is installed on the system
-
Determine installed versionRight-click the toolbox executable and select Properties > Details on Windows to view the File Version. On macOS, right-click the app > Get Info to see the Version. On Linux, check the version within the application itself via Help > About, or inspect the .version file in the installation directory.Affected if The version number is lower than 2.6 (e.g., 2.5.x, 2.4.x, 1.x, etc.)
-
Identify SSH plugin statusOpen JetBrains Toolbox and navigate to Settings or Preferences. Look for the SSH plugin or SSH functionality listed under Plugins, Tools, or Settings. On the Tools tab, check if SSH-related integration is enabled or configured.Affected if The SSH plugin is present, enabled, or has been used at least once to manage SSH connections
-
Confirm vulnerability applicabilityReview the context: this vulnerability specifically affects the SSH plugin functionality. If you have used or configured SSH connections through JetBrains Toolbox (e.g., for cloning repositories or SSH shortcuts), the attack surface is present.Affected if The SSH plugin is in use and the installed version is below 2.6
A user is affected if JetBrains Toolbox version 2.6 or later is NOT installed AND the SSH plugin has been enabled or used on the system.

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 · scoped2.6
Upgrade JetBrains Toolbox App to version 2.6 or later to remediate this vulnerability. Until the upgrade is applied, avoid using the SSH plugin with untrusted connections.
2.6
- Open JetBrains Toolbox App
- Click on the settings icon (gear) or navigate to the Toolbox settings
- Check for updates or navigate to the version information
- Update to version 2.6 or later
- Restart the application to ensure the update is fully applied
