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
Craft is a flexible, user-friendly CMS for creating custom digital experiences on the web and beyond. Users of affected versions are affected by this vulnerability if their php.ini configuration has `register_argc_argv` enabled. For these users an unspecified remote code execution vector is present. Users are advised to update to version 3.9.14, 4.13.2, or 5.5.2. Users unable to upgrade should disable `register_argc_argv` to mitigate 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 confidence

Craft CMS versions prior to 3.9.14, 4.13.2, or 5.5.2 contain an unspecified remote code execution vulnerability that is only exploitable when the PHP configuration directive `register_argc_argv` is enabled. This PHP setting allows PHP scripts to access command-line arguments.

MitigationEither upgrade Craft CMS to version 3.9.14, 4.13.2, or 5.5.2, or disable the `register_argc_argv` directive in php.ini and restart the PHP service.

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 installed Craft CMS version
    Locate the version file in your Craft installation (composer.json or craft/app/etc/app.xml) or view the version in the Craft admin panel under Utilities > System Report
    Affected if The installed version is 3.0.0 through 3.9.13, 4.0.0 through 4.13.1, or 5.0.0 through 5.5.1 (meaning it falls within the affected ranges)
  2. Verify PHP register_argc_argv setting
    Run phpinfo() or inspect your php.ini file to determine the value of the register_argc_argv directive
    Affected if register_argc_argv is set to On or enabled in the PHP configuration

A user is affected if their Craft CMS version is in one of the affected ranges AND PHP's register_argc_argv directive is enabled in their environment.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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.

Interim mitigation

Either upgrade Craft CMS to version 3.9.14, 4.13.2, or 5.5.2, or disable the `register_argc_argv` directive in php.ini and restart the PHP service.

Recommended fix High confidence

Upgrade to Craft CMS 3.9.14, 4.13.2, or 5.5.2 depending on your current major version

  1. 1. Identify your current Craft CMS version by checking the composer.json file or the admin dashboard.
  2. 2. Create a complete backup of your database and files before proceeding with any upgrade.
  3. 3. For Craft CMS 3.x users: Update to version 3.9.14 by running composer require craftcms/cms:^3.9.14 in your project directory.
  4. 4. For Craft CMS 4.x users: Update to version 4.13.2 by running composer require craftcms/cms:^4.13.2 in your project directory.
  5. 5. For Craft CMS 5.x users: Update to version 5.5.2 by running composer require craftcms/cms:^5.5.2 in your project directory.
  6. 6. Run composer update to install the new version and its dependencies.
  7. 7. Run any pending database migrations using ./craft migrate/all as needed.
  8. 8. Verify the upgrade was successful by checking the version in the admin dashboard.
