Public exploit or detection template: none known
Published: 2017-12-13 · updated 2026-06-17
Weakness: CWE-862

Description

In Octopus Deploy before 4.1.3, the machine update process doesn't check that the user has access to all environments. This allows an access-control bypass because the set of environments to which a machine is scoped may include environments in which the user lacks access.

Affected products

Octopus Deploy: before 4.1.3 — fixed in 4.1.3

How to fix

Upgrade to a fixed version: Octopus Deploy 4.1.3. Check the vendor advisory for mitigations.
