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. Verify Diff module is installed
    In the Drupal admin interface, navigate to Extend or use Drush: `drush pm-list --type=module --status=enabled | grep diff`. Alternatively, check for the diff.module file in the modules/contrib/diff directory of your Drupal installation.
    Affected if The Diff module is installed and enabled.
  2. Determine installed Diff module version
    Check the diff.info.yml file in the modules/contrib/diff directory, or run: `drush pm:info diff`. The version is listed in the 'Version' or 'core' and 'version' fields.
    Affected if The Diff module is present and has a version number.
  3. Compare version against affected ranges
    Compare the installed version to the affected ranges: versions lower than 1.8.0 (such as 1.7.x, 1.6.x, etc.) and version 2.0.0 are vulnerable. Versions 1.8.0 and later (excluding 2.0.0) are not affected.
    Affected if The installed version is less than 1.8.0 OR equals exactly 2.0.0.

A user is affected if the Drupal Diff module is installed and its version is either below 1.8.0 or exactly 2.0.0.
