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 security vulnerability has been detected in Shazwazza Smidge up to 4.5.1. The impacted element is an unknown function of the component Bundle Handler. The manipulation of the argument Version leads to path traversal. Remote exploitation of the attack is possible. Upgrading to version 4.6.0 is sufficient to resolve this issue. It is recommended to upgrade the affected component.

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

Path traversal vulnerability in Shazwazza Smidge library's Bundle Handler component allows attackers to manipulate the Version argument to access files outside the intended directory via directory traversal sequences (e.g., ../). The flaw is exploitable remotely with medium complexity (CVSS 6.3).

MitigationUpgrade Smidge to version 4.6.0 or later to obtain the patched version of the Bundle Handler component. Verify bundle functionality after upgrade.

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 if Smidge library is present
    Search project references, NuGet packages, or bin directory for Shazwazza.Smidge or Smidge DLLs. Check project.csproj or packages.config for Smidge dependency.
    Affected if Smidge library is found in the project dependencies or bin folder.
  2. Determine installed Smidge version
    Open the Smidge DLL properties in the bin folder, check NuGet package version in packages.config, or run 'dotnet list package' if using .NET CLI. Compare against the affected range (versions prior to 4.6.0).
    Affected if Installed version is below 4.6.0 (e.g., 4.5.x, 4.4.x, earlier).
  3. Verify Bundle Handler is accessible
    Check the application's routing/configuration for Smidge bundle endpoints. Look for routes like '/sb/' or '/api/bundle/' in Startup.cs, Program.cs, or web.config. Test accessing a bundle URL with a Version parameter.
    Affected if Bundle Handler endpoint is exposed and accessible via web request.
  4. Check if Version parameter accepts traversal
    Attempt a test request to the bundle handler with a Version argument containing '../' sequences (e.g., /sb/?v=../../web.config). Observe if the application returns files outside the designated smidge folder.
    Affected if The application returns files from outside the Smidge directory when using '../' in the Version parameter.

A user is affected if they have Smidge version below 4.6.0 installed AND the Bundle Handler endpoint is web-accessible, allowing path traversal via the Version argument.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Smidge to version 4.6.0 or later to obtain the patched version of the Bundle Handler component. Verify bundle functionality after upgrade.

Recommended fix High confidence

4.6.0

  1. 1. Ensure you have a complete backup of your project and database before proceeding with the upgrade.
  2. 2. Identify the project file that manages NuGet dependencies (typically the .csproj file or packages.config).
  3. 3. Update the Shazwazza.Smidge NuGet package reference to version 4.6.0 or later.
  4. 4. If using Package Manager Console, run: Update-Package Shazwazza.Smidge -Version 4.6.0
  5. 5. If using dotnet CLI, run: dotnet add package Shazwazza.Smidge --version 4.6.0
  6. 6. Alternatively, manually update the version number in your project file to 4.6.0 and restore packages.
  7. 7. Rebuild the solution to ensure the new package version is correctly integrated.
  8. 8. Test the application thoroughly, particularly the bundle handler functionality, to verify the path traversal vulnerability is resolved.
