CVE-2021-36483
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 · uneditedDevExpress.XtraReports.UI through v21.1 allows attackers to execute arbitrary code via insecure deserialization.
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 confidenceDevExpress.XtraReports.UI through v21.1 contains an insecure deserialization vulnerability where untrusted serialized data is processed without proper validation, allowing authenticated attackers to execute arbitrary code by injecting malicious serialized objects.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Locate DevExpress.XtraReports.UI componentSearch for DevExpress.XtraReports.UI.dll in the application bin directory, or inspect the project references/packages.config for DevExpress.XtraReports.UI package references. On Windows, also check the GAC or installed assemblies in the .NET assembly folder.Affected if The DLL or package reference exists in the environment, indicating the component is installed.
-
Identify the installed versionRight-click the DevExpress.XtraReports.UI.dll file, select Properties, then navigate to the Details tab to view the File Version. Alternatively, if using NuGet, run 'Get-Package DevExpress.XtraReports.UI' in the Package Manager Console to retrieve the installed version number.Affected if The version is 21.1 or lower, meaning the unpatched version is in use.
-
Verify deserialization data flowReview application code and configuration to determine whether the application accepts, deserializes, or processes serialized objects from external or untrusted sources. Check for endpoints, web services, or file upload handlers that handle serialized data (BinaryFormatter, ObjectStateFormatter, XML serialization, or custom deserializers).Affected if The application processes untrusted serialized data through DevExpress.XtraReports.UI, creating the conditions for exploitation.
The environment is affected if DevExpress.XtraReports.UI version 21.1 or lower is present AND the application processes serialized data from untrusted sources.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataUpgrade DevExpress.XtraReports.UI to version 21.2 or later which contains the security patch for this vulnerability. If immediate upgrading is not feasible, implement input validation and network-level access controls to limit exposure to untrusted deserialization sources.
