CVE-2024-51417
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 · uneditedAn issue in System.Linq.Dynamic.Core before 1.6.0 allows remote access to properties on reflection types and static properties/fields.
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 confidenceSystem.Linq.Dynamic.Core before version 1.6.0 contains a vulnerability allowing unauthorized access to properties on reflection types and static properties/fields, potentially exposing sensitive system information or enabling further exploitation.

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 checksWork through these to decide whether this CVE applies to you.
-
Find the installed version of System.Linq.Dynamic.CoreInspect your project dependencies: check the .csproj file for PackageReference, packages.config, or the obj/project.assets.json file. In deployed apps, check the appsettings.deps.json or look for the System.Linq.Dynamic.Core.dll in the bin folder and view its file properties for version info.Affected if The library version is present and is lower than 1.6.0 (for example 1.5.0, 1.4.0, etc.)
-
Confirm the library is in your dependency treeSearch your codebase for references to System.Linq.Dynamic.Core or its namespace 'System.Linq.Dynamic'. Look for using statements, package references, or runtime dependency resolution.Affected if The library appears in your dependencies or code imports
-
Identify usage of DynamicExpression parsingSearch your codebase for calls to DynamicExpression.Parse or similar methods from the System.Linq.Dynamic namespace, especially where user-controlled input is passed as the expression string.Affected if Your code parses dynamic LINQ expressions from external input or untrusted sources
-
Check for reflection-based property access patternsReview code that uses the library to access properties via string names, GetProperty calls, or similar reflection operations through DynamicLINQ.Affected if The application uses the library to access object properties dynamically by name
You are affected if System.Linq.Dynamic.Core version 1.6.0 or later is not installed AND your application uses the library to parse dynamic expressions or access properties via reflection.

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 · scopedUpgrade System.Linq.Dynamic.Core to version 1.6.0 or later to remediate the unauthorized reflection access.
System.Linq.Dynamic.Core version 1.6.0 or later
- 1. Identify the current version of System.Linq.Dynamic.Core in your project by checking your .csproj file or NuGet package references
- 2. If the current version is before 1.6.0, update the package reference to version 1.6.0 or later
- 3. In your .csproj file, locate the System.Linq.Dynamic.Core package reference and update the Version attribute to 1.6.0 or newer
- 4. Run 'dotnet restore' or 'dotnet build' to fetch the updated package and verify compatibility
- 5. Test your application to ensure the dynamic LINQ functionality works as expected after the upgrade
