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 has been found in nextlevelbuilder GoClaw 3.13.3-beta.3. Affected by this vulnerability is the function bytePlusDownloadVideo of the file internal/tools/create_video_byteplus.go of the component invoke Endpoint. The manipulation of the argument output.video_url leads to server-side request forgery. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used.

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

Server-side request forgery (SSRF) in the bytePlusDownloadVideo function where the output.video_url argument is not validated before being used in server-side requests, allowing remote attackers to make the server request arbitrary URLs.

MitigationImplement strict input validation and allowlist filtering on the video_url parameter to restrict requests to trusted domains only; also apply network segmentation to limit SSRF impact.

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. Locate the bytePlusDownloadVideo function
    Search your codebase or application modules for the function name 'bytePlusDownloadVideo' - inspect source code, binaries, or loaded libraries to confirm its presence in your environment
    Affected if The function exists in your deployed application code or libraries
  2. Inspect video_url parameter handling
    Examine the function implementation to see how the output.video_url argument is processed - look for any validation, sanitization, or filtering logic applied to this parameter before server-side requests are made
    Affected if No input validation or allowlist filtering is performed on the video_url parameter before it is used in HTTP requests
  3. Confirm external request capability
    Review the function code to verify that it actually performs HTTP/HTTPS requests using the video_url value - check for use of fetch, curl, file_get_contents, or similar network request mechanisms
    Affected if The function makes network requests using the unsanitized video_url value
  4. Test URL injection possibility
    If you have testing capability, attempt to provide a non-video URL (such as http://169.254.169.254/) as the video_url parameter and observe whether the server makes a request to that arbitrary URL
    Affected if The server successfully makes requests to attacker-controlled URLs
  5. Check network segmentation
    Review your firewall rules, network policies, or application-level restrictions to determine if outbound requests from the server are restricted to trusted domains only
    Affected if No network-level restrictions exist to prevent requests to arbitrary internal or external URLs

You are affected if the bytePlusDownloadVideo function exists in your environment and the video_url parameter is used in server-side requests without validation or network restrictions.
