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 · unedited
Improper neutralization of special elements used in an OS command ('command injection') in Cursor allows an unauthorized attacker to execute commands that are outside of those specified in the allowlist, resulting in arbitrary code execution.

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 confidence

Cursor contains a command injection vulnerability where improper neutralization of special elements in OS command execution allows attackers to bypass an existing allowlist mechanism and execute arbitrary commands on the host system.

MitigationImplement strict input validation and sanitization for all command arguments, ensuring the allowlist enforcement cannot be bypassed. Use parameterized command execution APIs or safe wrapper functions that prevent injection of shell metacharacters.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if Cursor is installed
    On Windows: look for Cursor in Program Files or AppData folders. On macOS: check /Applications for Cursor.app. On Linux: check common installation paths like /usr/bin/cursor or ~/.local/share/cursor.
    Affected if Cursor is found on the system
  2. Determine installed Cursor version
    On Windows: right-click Cursor.exe, select Properties, view Details tab for File version. On macOS: right-click Cursor.app, select Get Info, view Version. On Linux: run cursor --version or check the app image metadata.
    Affected if A version number is retrieved from the Cursor installation
  3. Compare version against vulnerable range
    Since no specific CVE version range was provided, compare your installed version against the latest patched version noted in Cursor release notes or security advisories for around 2025.
    Affected if Your version is older than the patched version and thus potentially vulnerable
  4. Identify if command execution feature is in use
    Cursor may have features that execute OS commands (e.g., terminal integration, build/run tasks, extensions that run shell commands). Review Cursor settings.json or check for terminal panels that execute commands.
    Affected if You use Cursor features that invoke OS commands on the host system
  5. Verify allowlist configuration exists
    The vulnerability involves bypassing an allowlist for command execution. Check Cursor user settings for any command allowlist, whitelist, or execution policy configurations.
    Affected if An allowlist or whitelist for commands is configured in Cursor settings

You are affected if you have an older unpatched version of Cursor installed and use its command execution features.
