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
Craftql v1.3.7 and before is vulnerable to Server-Side Request Forgery (SSRF) which allows an attacker to execute arbitrary code via the vendor/markhuot/craftql/src/Listeners/GetAssetsFieldSchema.php file

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

CraftQL v1.3.7 and earlier contains an SSRF vulnerability in the GetAssetsFieldSchema.php file that allows an attacker to induce the server to make arbitrary HTTP requests to internal or external resources, potentially exposing internal services or facilitating further attacks.

MitigationUpgrade to a patched version of CraftQL; if unavailable, implement strict URL validation and network segmentation to prevent the affected code from making unauthorized requests.

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. Identify CraftQL installation
    Check your Craft CMS plugins directory or composer.json for the presence of the craftql package. Common paths include /vendor/craftcms/craftql/ or check composer.lock for craftql entry.
    Affected if CraftQL plugin is present in the installation
  2. Determine CraftQL version
    Check the installed CraftQL version via composer.json, composer.lock, or the Craft CMS plugin store. Compare the version number against v1.3.7 - versions 1.3.7 and earlier are affected.
    Affected if Installed version is 1.3.7 or earlier
  3. Locate vulnerable file
    Search for the GetAssetsFieldSchema.php file in the CraftQL source code. In a typical installation, this would be at /vendor/craftcms/craftql/src/fields/GetAssetsFieldSchema.php or similar path under the craftql package directory.
    Affected if GetAssetsFieldSchema.php exists in the CraftQL plugin directory
  4. Check if GraphQL field is exposed
    Verify that the GraphQL API endpoint is accessible and that asset-related GraphQL queries can be executed. The SSRF vulnerability in GetAssetsFieldSchema.php is triggered through GraphQL field schema generation.
    Affected if GraphQL API is enabled and asset field queries are accessible without additional authentication beyond standard Craft CMS user authentication

A user is affected if CraftQL v1.3.7 or earlier is installed, the GetAssetsFieldSchema.php file is present, and the GraphQL API with asset field capabilities is enabled.

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.
