CVE-2026-42823
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 access control in Azure Logic Apps 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 confidenceAzure Logic Apps contains an improper access control vulnerability that allows an authenticated attacker to escalate privileges. The vulnerability involves broken access control mechanisms within the Logic Apps service, potentially enabling a user with limited permissions to gain higher-level access to resources or functionalities they should not have.

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 Logic Apps resources in your Azure subscriptionRun 'az resource list --resource-type Microsoft.Logic/workflows' to list all Logic App resources, or check the Azure Portal under Logic Apps serviceAffected if Any Logic App resource exists in the subscription - all versions are affected by this vulnerability
-
Review RBAC role assignments on Logic App resourcesUse Azure Portal or run 'az role assignment list --scope <logic-app-resource-id>' to list all role assignments for each Logic App. Focus on identifying non-standard or overly permissive assignmentsAffected if Users or service principals have role assignments that grant more than Reader access (such as Contributor or Owner) on Logic App resources
-
Check for privilege escalation paths in Logic App identitiesExamine whether Logic Apps have managed identities enabled and what permissions those identities have to other Azure resources. Run 'az logicapp show --name <name> --resource-group <rg>' and check the 'identity' propertyAffected if Logic Apps with system or user-assigned identities have broad permissions to access other resources without proper justification
-
Audit Logic App workflow trigger and action authorizationsReview the workflow JSON definition (via 'az logicapp workflow show') to identify any triggers or actions that may not validate authorization for each operation, particularly HTTP or custom connector actionsAffected if Logic App workflows contain HTTP triggers, webhook triggers, or custom connector actions that process requests without explicit authorization checks
You are affected if you have any Azure Logic Apps deployed with users granted Contributor or Owner roles, or if your Logic Apps have workflows with triggers/actions that do not enforce per-operation authorization validation.
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 dataReview and enforce role-based access control (RBAC) assignments for Azure Logic Apps, implement least-privilege principles, and apply any available Microsoft security updates or patches for Logic Apps. Validate that all Logic App triggers and actions properly validate authorization for each operation.
