CVE-2025-29826
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 · uneditedImproper handling of insufficient permissions or privileges in Microsoft Dataverse allows an authorized attacker to elevate privileges 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 confidenceA privilege escalation vulnerability in Microsoft Dataverse allows an authenticated attacker to elevate their privileges beyond what their account is authorized for, due to improper handling of permission checks. This could enable unauthorized access to data or administrative functions within the Dataverse environment.

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 Dataverse environment versionIn the Power Platform admin center, select your environment and view the version information under 'Details', or use the Power Apps Maker Portal > Settings > About Microsoft Dataverse. Alternatively, query the Dataverse Web API endpoint: /api/discovery/v1.0/instancesAffected if The installed version is lower than 3.4.0.1406
-
Review user role assignmentsUsing the Power Platform Admin Center, navigate to the Dataverse environment > Users > See all users, then check each user's security role. Or use the Dataverse Web API to query the 'role' table and 'systemuser' table joined to identify role associations.Affected if Any user account has been assigned privileges beyond what their job function requires, or role assignments do not follow least-privilege principles
-
Audit recently added or modified security rolesIn the Power Platform Admin Center, use the 'Audit' feature to review security role changes. Query the 'audit' table filtering by 'action' = 'Update' and 'objecttype' = 'role' for recent changes.Affected if Unapproved modifications to security roles exist, or roles with elevated permissions were created recently
-
Check for privilege escalation indicators in audit logsEnable and review Dataverse audit logs for 'Securities' category. Look for instances where users accessed data or performed actions outside their assigned security role permissions.Affected if Audit logs show users executing operations or accessing data that their assigned security roles should not permit
You are affected if your Microsoft Dataverse version is below 3.4.0.1406 AND your environment contains authenticated users with elevated or misconfigured role-based access control assignments.

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 · scoped3.4.0.1406
Apply Microsoft's forthcoming patch for Dataverse; in the interim, audit role-based access control (RBAC) assignments and enforce least-privilege principles to limit potential blast radius.
3.4.0.1406
- Upgrade Microsoft Dataverse to version 3.4.0.1406 or later to address the privilege escalation vulnerability
