CVE-2017-17665
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
