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
A vulnerability was found in birkir prime up to 0.4.0.beta.0. The impacted element is an unknown function of the file /graphql of the component GraphQL Array Based Query Batch Handler. The manipulation results in denial of service. The attack can be executed remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.

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

A denial of service vulnerability exists in birkir prime (up to 0.4.0.beta.0) within the GraphQL Array Based Query Batch Handler component at the /graphql endpoint. The vulnerability involves an unknown function that can be exploited remotely to cause DoS, and a public exploit is available.

MitigationImplement GraphQL query complexity analysis, depth limiting, and request rate limiting on the /graphql endpoint to mitigate DoS. Consider request timeouts and batching restrictions until the vendor releases a patch.

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 birkir prime installation
    Locate the application running in your environment that uses the birkir prime software package. Check your application inventory, container registry, or deployment manifests for references to birkir prime.
    Affected if birkir prime is present in your environment
  2. Check birkir prime version
    Identify the installed version of birkir prime by examining your package.json, requirements.txt, Gemfile, or equivalent dependency file. Also check the running application's About page, headers, or API version endpoint if available.
    Affected if the installed version is 0.4.0 or any version up to and including 0.4.0.beta.0
  3. Confirm GraphQL endpoint exposure
    Attempt to access the /graphql endpoint on your birkir prime server by sending a POST request to http(s)://yourserver/graphql with a valid GraphQL query or introspection query. Also check your web server logs for requests to this path.
    Affected if the /graphql endpoint is accessible and responds to requests
  4. Verify Array Based Query Batch Handler is active
    Send a GraphQL batch query (multiple operations in a single array) to the /graphql endpoint. Observe if the endpoint accepts and processes array-based batch requests. Check if your GraphQL configuration enables batch query handling.
    Affected if the /graphql endpoint accepts and processes array-based batch queries

You are affected if birkir prime version 0.4.0 or lower is running and the /graphql endpoint with its Array Based Query Batch Handler is exposed and functional.

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.

From vendor data
Upgrade available Upgrade to a release after 0.4.0
Interim mitigation

Implement GraphQL query complexity analysis, depth limiting, and request rate limiting on the /graphql endpoint to mitigate DoS. Consider request timeouts and batching restrictions until the vendor releases a patch.
