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
The validate JSON endpoint of the Secvisogram csaf-validator-service in versions < 0.1.0 processes tests with unexpected names. This insufficient input validation of requests by an unauthenticated remote user might lead to a partial DoS of the service. Only the request of the attacker is affected by this vulnerability.

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 validate JSON endpoint in Secvisogram csaf-validator-service versions prior to 0.1.0 insufficiently validates input by processing test names that fall outside expected parameters. An unauthenticated remote attacker can submit specially crafted requests with unexpected test names, causing the service to consume excessive resources and resulting in a partial denial of service affecting only the attacker's own request.

MitigationUpgrade to csaf-validator-service version 0.1.0 or later which implements proper input validation to reject tests with unexpected names at the validate JSON 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 installed version of csaf-validator-service
    Check the version of the csaf-validator-service or csaf-validator-lib package installed in your environment using your package manager (npm, pip, or similar). Common commands include: npm list csaf-validator-service, pip show csaf-validator-lib, or checking package.json/package-lock.json for the version field.
    Affected if The installed version is less than 0.1.0
  2. Confirm the validate JSON endpoint exists
    Locate the HTTP endpoints exposed by the csaf-validator-service. This is typically found in the service's API documentation, source code, or by inspecting the running service's route definitions. Look for endpoints that accept JSON validation requests.
    Affected if The service exposes a validate JSON endpoint that accepts test name parameters
  3. Check if the service accepts arbitrary test names
    Examine the source code or configuration of the csaf-validator-service for the validate JSON endpoint handler. Look for input validation logic that processes the 'test' or 'test_name' parameter. Determine whether the code validates against an allowlist or rejects unexpected values.
    Affected if The endpoint processes test names without rejecting unexpected values or without proper allowlist validation
  4. Determine if the service is network accessible
    Verify whether the csaf-validator-service is listening on a network interface and is reachable from untrusted networks. Check if authentication is required for the validate JSON endpoint.
    Affected if The service is network-accessible without authentication and accepts requests to the validate JSON endpoint

You are affected if your installed csaf-validator-service or csaf-validator-lib version is below 0.1.0 AND the validate JSON endpoint is exposed and accepts arbitrary test name parameters without proper validation.

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.

dbcve · scoped
Upgrade available Upgrade to 0.1.0 or later
Fixed in 0.1.0
Interim mitigation

Upgrade to csaf-validator-service version 0.1.0 or later which implements proper input validation to reject tests with unexpected names at the validate JSON endpoint.

Recommended fix Moderate confidence

csaf-validator-lib version 0.1.0 or later

  1. Identify the current version of csaf-validator-lib in your project dependencies
  2. Update the dependency to version 0.1.0 or later using your package manager (e.g., npm install csaf-validator-lib@latest or specific version)
  3. Verify the upgrade by checking the installed package version
  4. Run existing tests to ensure the service still functions correctly after the upgrade
