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
In Octopus Deploy versions 3.2.11 - 4.1.5 (fixed in 4.1.6), an authenticated user with ProcessEdit permission could reference an Azure account in such a way as to bypass the scoping restrictions, resulting in a potential escalation of privileges.

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

In Octopus Deploy versions 3.2.11 through 4.1.5, an authenticated user with ProcessEdit permission could reference an Azure account in a manner that bypasses configured scoping restrictions, enabling privilege escalation beyond what the user's role should permit.

MitigationUpgrade Octopus Deploy to version 4.1.6 or later. As a compensating control, audit and restrict ProcessEdit permissions to only trusted, necessary users until the upgrade can be completed.

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. Check Octopus Deploy version
    Locate the Octopus Deploy server and identify its version number (typically visible in the web UI header or in the server's About/Information page)
    Affected if The installed version is between 3.2.11 and 4.1.5 inclusive
  2. Verify ProcessEdit permission exists
    In the Octopus Deploy web interface, navigate to Users or Roles configuration and check if any user role includes the ProcessEdit permission
    Affected if Any user account possesses the ProcessEdit permission
  3. Identify Azure account configurations
    In the Octopus Deploy infrastructure settings, examine any configured Azure accounts and their scoping restrictions (account tenant or subscription limitations)
    Affected if Azure accounts are configured with scoping restrictions that should limit access
  4. Audit user-role assignments for ProcessEdit
    Review which users are assigned roles containing ProcessEdit permission, particularly those who should have limited scope
    Affected if Users with ProcessEdit permission exist alongside Azure accounts with scoping restrictions configured

You are affected if running Octopus Deploy version 3.2.11 through 4.1.5 with users possessing ProcessEdit permission and Azure accounts configured with scoping restrictions that could be bypassed.
