CVE-2025-43014
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 the SSH plugin established connections without sufficient user confirmation
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 · moderate confidenceThe JetBrains Toolbox App SSH plugin (versions before 2.6) initiates SSH connections without properly prompting for user confirmation, potentially allowing connections to unintended or malicious SSH servers.

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.
-
Identify JetBrains Toolbox installationLocate the JetBrains Toolbox application on the system. Common installation paths include: Windows: %LOCALAPPDATA%\JetBrains\Toolbox\ or C:\Program Files\JetBrains\Toolbox\, macOS: /Applications/JetBrains/Toolbox.app or ~/Library/Application Support/JetBrains/Toolbox/, Linux: ~/.local/share/JetBrains/Toolbox/ or /opt/jetbrains/toolbox/Affected if JetBrains Toolbox is found on the system
-
Determine installed versionCheck the version of the installed JetBrains Toolbox application. On Windows, right-click the executable and select Properties > Details > File Version. On macOS, right-click the app > Get Info > Version. On Linux, check the version file in the installation directory or run the binary with --version if supported.Affected if Version is below 2.6 (e.g., 2.5.x, 2.4.x, etc.)
-
Verify SSH plugin presenceExamine the JetBrains Toolbox configuration for the SSH plugin. Look for SSH-related settings in the Toolbox settings, configuration files, or plugins directory within the installation folder.Affected if SSH plugin is installed or enabled in Toolbox
-
Check SSH connection behaviorIf the SSH plugin is present, test by initiating an SSH connection through Toolbox. Observe whether a user confirmation prompt appears before the connection is established.Affected if No user confirmation prompt appears before SSH connection initiation
User is affected if JetBrains Toolbox version is below 2.6 AND the SSH plugin is installed/enabled, as the lack of confirmation prompts could allow unintended connections.

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 receive the fix. Until upgraded, verify all SSH connections initiated by the tool and avoid using the SSH plugin with untrusted hosts.
2.6
- Download the latest JetBrains Toolbox App from the official JetBrains website (www.jetbrains.com/toolbox)
- Run the installer to upgrade your existing installation
- Launch Toolbox and verify the version number shows 2.6 or later
- If prompted, restart the application to ensure the SSH plugin update takes effect
