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
Deserialization of untrusted data in Microsoft Dataverse allows an authorized attacker to execute code over a network.

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 deserialization vulnerability in Microsoft Dataverse allows an authenticated attacker to execute arbitrary code remotely. The flaw stems from unsafe deserialization of data processed by the Dataverse platform, enabling remote code execution with the privileges of the affected component.

MitigationMicrosoft customers should monitor for official security updates from Microsoft and review Dataverse data connections and plug-ins for suspicious activity. Apply vendor patches upon release.

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 Microsoft Dataverse usage
    Review your environment to determine if Microsoft Dataverse (part of Microsoft Power Platform) is actively in use. Check for Dataverse databases, connected Power Apps, Power Automate flows, or any applications that leverage Dataverse as their data backend.
    Affected if Your organization uses Microsoft Dataverse in any capacity, as all versions are affected by this deserialization vulnerability.
  2. Audit Dataverse plug-ins
    Use the Power Platform Admin Center or Dataverse API to enumerate registered plug-ins and custom workflows. Review the Plug-in Registration Tool (PRT) for any unauthorized or suspicious plug-ins that may indicate exploitation attempts.
    Affected if Unknown, untrusted, or newly registered plug-ins are present that were not intentionally deployed by your administrators.
  3. Review Dataverse data connections
    Examine all data connections and external data sources configured in Dataverse environments. Check for unexpected or unauthorized connections that could be used to inject malicious serialized payloads.
    Affected if Unexpected data connections exist or connections to untrusted external sources are configured.
  4. Check Dataverse audit logs for exploitation indicators
    Search Dataverse audit logs for events related to deserialization-heavy operations, unusual plugin executions, or failed deserialization attempts. Look for patterns such as unexpected assembly loads, type instantiation from untrusted sources, or elevated error rates in plugin execution.
    Affected if Audit logs reveal suspicious plugin execution patterns, unauthorized assembly loads, or anomalous error patterns indicative of deserialization exploitation attempts.
  5. Review user authentication and session activity
    Since this vulnerability requires an authenticated attacker, review Azure AD sign-in logs and Dataverse audit history for unauthorized user sessions, especially from privileged accounts or unusual IP addresses.
    Affected if Evidence exists of unauthorized authentication, credential misuse, or session hijacking attempts targeting Dataverse.

If your organization uses Microsoft Dataverse, you are potentially affected by this vulnerability; detection should focus on identifying unauthorized plug-ins, suspicious data connections, and anomalous audit log activity indicative of exploitation attempts.
