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
Missing Authorization vulnerability in Milestone Systems XProtect VMS allows users with read-only access to Management Server to have full read/write access to MIP Webhooks API.

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

This is a broken access control vulnerability where the MIP Webhooks API in Milestone Systems XProtect VMS fails to properly enforce authorization checks. Users granted read-only permissions to the Management Server can bypass these restrictions and obtain full read/write access to the Webhooks API, allowing them to create, modify, or delete webhook configurations they should not be permitted to touch.

MitigationImplement proper authorization validation in the MIP Webhooks API to enforce the read-only permissions assigned to users at the Management Server level, ensuring all API write operations validate the user's actual permission tier before execution.

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. Identify XProtect VMS version
    Check the installed version of Milestone XProtect VMS via the Management Server or installer information
    Affected if Running any version of XProtect VMS that includes the MIP Webhooks API feature
  2. Verify MIP Webhooks API is enabled
    Inspect the Management Server configuration or logs to confirm the MIP Webhooks API module is installed and active
    Affected if The MIP Webhooks API module is present and running on the Management Server
  3. Identify read-only user accounts
    Review user accounts in the Management Server that are assigned read-only permissions at the server level
    Affected if There exist users granted read-only permission tier on the Management Server
  4. Test Webhooks API access from read-only account
    Using a read-only user account, attempt a POST, PUT, or DELETE request to the MIP Webhooks API endpoint (e.g., /api/webhooks or similar endpoint)
    Affected if A read-only user can successfully create, modify, or delete webhook configurations via the API
  5. Audit webhook configurations for unauthorized changes
    Review webhook configuration audit logs or compare current webhooks against known-good baseline to identify changes made by read-only users
    Affected if Webhook configurations show modifications authored by read-only permission accounts

A user is affected if their XProtect VMS deployment has the MIP Webhooks API enabled and any read-only permission user can successfully perform write operations (create/modify/delete) against the Webhooks API.
