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
In JetBrains IntelliJ IDEA before 2021.2.4, local code execution (without permission from a user) upon opening a project 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 · moderate confidence

IntelliJ IDEA versions before 2021.2.4 contained a vulnerability allowing local code execution without user permission when opening a malicious project. An attacker could craft a project file that triggers arbitrary code execution upon project opening in the IDE.

MitigationUpdate IntelliJ IDEA to version 2021.2.4 or later. Avoid opening untrusted or unfamiliar projects from untrusted sources.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 your installed IntelliJ IDEA version
    Open IntelliJ IDEA and navigate to Help > About (or on macOS, IntelliJ IDEA > About). The version number is displayed in the dialog that appears. Alternatively, check the installation directory or your system's installed programs list for the version information.
    Affected if The displayed version is earlier than 2021.2.4 (for example, 2021.2, 2021.1, 2020.3, etc.)
  2. Verify the full version number including patch
    In the About dialog, note the full version string which includes the patch number (for example, 2021.2.3). Compare this against 2021.2.4.
    Affected if The version is 2021.2.3 or earlier, meaning the patch level is less than 4
  3. Assess whether you open projects from untrusted sources
    Consider your typical workflow: do you occasionally open project files, repositories, or ZIP archives from unfamiliar or untrusted sources, or are all your projects from known trusted origins?
    Affected if You open projects from untrusted or unfamiliar sources and your version is before 2021.2.4

You are affected if your IntelliJ IDEA version is any release before 2021.2.4 and you open projects from untrusted sources, as the vulnerability triggers simply by opening a malicious project file.

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.

Upgrade available Upgrade to 2021.2.4 or later
Fixed in 2021.2.4
Interim mitigation

Update IntelliJ IDEA to version 2021.2.4 or later. Avoid opening untrusted or unfamiliar projects from untrusted sources.

Recommended fix High confidence

2021.2.4 (build 212.5284.40)

  1. Open IntelliJ IDEA and navigate to Help > Check for Updates
  2. If an update is available, download and install version 2021.2.4 or later
  3. Alternatively, download the fixed version directly from jetbrains.com/idea/download/
  4. Restart IntelliJ IDEA after the update completes
  5. Verify the version by going to Help > About and confirm the build number is 212.5284.40 or higher
Caveat Patch updates within the same minor version typically have minimal breaking changes; ensure your project plugins are compatible
