CVE-2025-30389
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 authorization in Azure Bot Framework SDK allows an unauthorized 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 confidenceImproper authorization vulnerability in Azure Bot Framework SDK enables an unauthenticated attacker to escalate privileges by bypassing authentication controls, potentially gaining unauthorized access to higher-privileged operations or resources within the Bot Framework 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.
-
Confirm Azure Bot Service deploymentEnumerate Azure resources using Azure CLI or portal to identify if Microsoft Azure Ai Bot Service or Azure Bot Framework SDK-based bots are provisioned in the subscriptionAffected if Azure Ai Bot Service or bot applications built on Azure Bot Framework are found in the environment
-
Review authentication settingsInspect the bot service authentication and authentication provider configuration through Azure Portal or Azure CLI - check if token validation and authentication middleware are properly configuredAffected if Authentication is disabled, set to None, or token validation is not enforced on the bot's messaging endpoint
-
Examine role-based access control assignmentsCheck the IAM role assignments for the Bot Service resource and associated Azure resources using 'az role assignment list --scope <bot-resource-id>' or equivalent portal viewAffected if Excessive or overly permissive roles are assigned, or anonymous/unauthenticated access is permitted to bot operations
-
Assess network exposureReview the bot's messaging endpoint network settings - check if the web app or Azure Bot Service channel endpoints are exposed to the public internet without proper network controls or IP restrictionsAffected if The bot service endpoint is publicly accessible without Azure Virtual Network, firewall, or authentication barriers
-
Verify channel configurationInspect enabled channels (Direct Line, Web Chat, Teams, etc.) in the Azure Bot Service channel configuration and verify channel authentication tokens are requiredAffected if Channels are configured without requiring authentication tokens or have insecure channel settings
A user is affected if they have deployed Microsoft Azure Ai Bot Service and have weak or misconfigured access controls on their bot service endpoints or channels.

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 proper authorization checks throughout Bot Framework implementations; ensure all API endpoints and bot operations validate user permissions before executing privileged actions; apply any Microsoft security updates for Azure Bot Framework SDK.
