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
Flag Forge is a Capture The Flag (CTF) platform. From versions 2.0.0 to before 2.3.1, the /api/resources endpoint previously allowed POST and DELETE requests without proper authentication or authorization. This could have enabled unauthorized users to create, modify, or delete resources on the platform. The issue has been fixed in FlagForge version 2.3.1.

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

The /api/resources endpoint in Flag Forge versions 2.0.0 through 2.3.0 lacks proper authentication and authorization checks on POST and DELETE HTTP methods, allowing any unauthenticated user to create, modify, or delete resources on the CTF platform.

MitigationUpgrade to Flag Forge version 2.3.1 or later, which includes the authentication/authorization fix for the /api/resources endpoint.

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 Flag Forge installation
    Locate Flag Forge in your environment by checking for the flagforge application, service, or container. Common locations include /opt/flagforge, /var/www/flagforge, or as a Docker container named flagforge.
    Affected if Flag Forge is installed on the system
  2. Determine installed Flag Forge version
    Check the version of Flag Forge by inspecting package.json, version.txt, the application binary, or the Docker image tag. Compare the version against the affected range: >= 2.0.0 and < 2.3.1.
    Affected if The installed version falls within 2.0.0 through 2.3.0
  3. Verify /api/resources endpoint exists
    Examine the application routing configuration or API route definitions to confirm the /api/resources endpoint is defined in the Flag Forge codebase.
    Affected if The /api/resources endpoint exists in the application
  4. Check if POST and DELETE methods are allowed on /api/resources
    Review the route handler code for /api/resources to determine if HTTP POST and DELETE methods have authentication/authorization decorators or middleware applied. Look for missing auth checks on these methods.
    Affected if POST and DELETE handlers on /api/resources lack authentication and authorization checks

A system is affected if Flag Forge version 2.0.0 through 2.3.0 is installed and the /api/resources endpoint permits unauthenticated POST and DELETE requests.

Upgrade available Upgrade to 2.3.1 or later
Fixed in 2.3.1
Interim mitigation

Upgrade to Flag Forge version 2.3.1 or later, which includes the authentication/authorization fix for the /api/resources endpoint.

Recommended fix High confidence

FlagForge version 2.3.1

  1. Upgrade FlagForge from any version >= 2.0 and < 2.3.1 to version 2.3.1 or later
  2. After upgrading, verify that the /api/resources endpoint now requires proper authentication and authorization for POST and DELETE requests
  3. Test that authenticated users with appropriate permissions can still create, modify, and delete resources as expected
