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
An issue in OneFlow-Inc. Oneflow v0.9.1 allows attackers to cause a Denial of Service (DoS) when index as a negative number exceeds the range of size.

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 bounds checking vulnerability in Oneflow v0.9.1 allows attackers to trigger a Denial of Service by using a negative index value that exceeds the array/list size, causing an out-of-bounds access that crashes the application.

MitigationImplement proper bounds validation before array/list indexing operations to ensure indices are within valid range, rejecting or handling negative indices that exceed the collection size.

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. Confirm Oneflow installation
    Identify if Oneflow is installed in your environment by checking for the Oneflow application or service
    Affected if Oneflow is not present in your environment
  2. Check installed version
    Retrieve the installed version of Oneflow and compare it to the affected version 0.9.1
    Affected if The installed version is exactly 0.9.1
  3. Determine input processing context
    Identify whether your Oneflow instance processes data containing index values or array/list references that could be manipulated
    Affected if The application accepts or processes index-based input from users or external sources
  4. Test for crash condition
    If input processing is present, attempt to provide a negative index value that exceeds the collection size to observe if it triggers a crash or out-of-bounds error
    Affected if A negative index exceeding the collection size causes the application to crash or become unresponsive

You are affected if you are running Oneflow version 0.9.1 and your instance processes input that could contain negative index values exceeding collection bounds.

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.

Mitigation

Implement proper bounds validation before array/list indexing operations to ensure indices are within valid range, rejecting or handling negative indices that exceed the collection size.
