CVE-2025-6810
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 · uneditedMescius ActiveReports.NET ReadValue Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Mescius ActiveReports.NET. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the implementation of the ReadValue method. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25246.
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 confidenceThe vulnerability exists in the ReadValue method of Mescius ActiveReports.NET, where user-supplied data is deserialized without proper validation. This insecure deserialization allows remote attackers to execute arbitrary code in the context of the current process by passing malicious serialized payloads to the ReadValue method.

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.
-
Identify installed Mescius ActiveReports.NET versionCheck the installed ActiveReports.NET version through the application's assembly information, NuGet package reference, or the installed program version in Windows Add/Remove Programs. Look for files named 'GrapeCity.ActiveReports*.dll' and check their version properties.Affected if The installed version is 18.1.1 or falls within the affected version range that includes 18.1.1
-
Locate ReadValue method usage in codeSearch application source code for calls to the ReadValue method, typically invoked as 'ReadValue()' or similar patterns in classes that inherit from or use ActiveReports functionality. Use IDE search or grep tools across the codebase.Affected if Code contains calls to the ReadValue method from ActiveReports.NET libraries
-
Determine if ReadValue receives external inputAudit the data source passed to ReadValue calls. Trace the parameter back to its origin - check if it comes from HTTP requests, user uploads, API calls, file imports, or other untrusted sources. Inspect the call chain in the code.Affected if ReadValue method is called with data originating from untrusted or remote sources such as user input, HTTP requests, or imported files
-
Verify network exposure of vulnerable endpointIdentify if the application component containing ReadValue is accessible over the network, exposed via web API, web service, or any network-facing interface. Check application configuration and deployed endpoints.Affected if The application component using ReadValue is network-accessible and can receive serialized payloads from external sources
You are affected if Mescius ActiveReports.NET version 18.1.1 is installed AND your code uses the ReadValue method with data that originates from untrusted or remote sources accessible over a network.

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 dataApply vendor patch when available; until then, validate all input to ReadValue method, implement network segmentation to limit exposure, and audit code that calls ReadValue for untrusted data sources.
