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 affected versions of Octopus Server it is possible to reveal the existence of resources in a space that the user does not have access to due to verbose error messaging.

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 affected Octopus Server versions, verbose error messages disclose whether resources exist in spaces where the authenticated user lacks access permissions, allowing enumeration of protected resources through differential error responses.

MitigationConfigure error handling to return generic messages that do not reveal resource existence or validate authorization before error generation for unauthorized access attempts.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 installed Octopus Server version
    Run the command: octopusd --version or check the About page in the Octopus web interface
    Affected if The version falls within < 2022.1.3264; >= 2022.2.0 and < 2022.2.8351; >= 2022.3.0 and < 2022.3.10586; or >= 2022.4.0 and < 2022.4.2898
  2. Confirm Spaces feature is in use
    Navigate to Configuration > Spaces in the Octopus web interface or query the Spaces API endpoint
    Affected if Multiple spaces exist and users have varying permission levels across those spaces
  3. Test error response consistency
    Attempt to access a resource (such as a project or environment) in a space where you lack permissions, then compare the error message to one from a non-existent resource in the same space
    Affected if Error messages differ between existing protected resources versus non-existent resources, revealing resource existence through verbose responses

The environment is affected if the installed Octopus Server version is within any of the listed vulnerable ranges and the server uses Spaces with users having limited permissions.

Fixed in 2022.1.32642022.2.83512022.3.10586
Interim mitigation

Configure error handling to return generic messages that do not reveal resource existence or validate authorization before error generation for unauthorized access attempts.

Recommended fix High confidence

2022.4.2898 or later (or any version >= the fixed release in your current branch: 2022.1.3264, 2022.2.8351, 2022.3.10586, or 2022.4.2898)

  1. 1. Backup your Octopus Server database and configuration files before proceeding with any upgrade.
  2. 2. Download the latest stable Octopus Server version (2022.4.2898 or later) from the official Octopus website.
  3. 3. Stop the Octopus Server service to ensure a clean upgrade process.
  4. 4. Run the installer for the new version, following the on-screen prompts.
  5. 5. Once installation completes, start the Octopus Server service.
  6. 6. Verify that the verbose error messaging vulnerability is fixed by attempting to access resources in a space without permission - error messages should no longer reveal resource existence.
  7. 7. Test that normal functionality continues to work as expected.
Caveat Standard minor version upgrade - review Octopus release notes for any deprecation notices in your version path
