In Octopus Deploy 2019.7.3 through 2019.7.9, in certain circumstances, an authenticated user with VariableView permissions could view sensitive values. This is fixed in 2019.7.10.

In Octopus Deploy 2019.4.0 through 2019.6.x before 2019.6.6, and 2019.7.x before 2019.7.6, an authenticated system administrator is able to view sensitive values by visiting a server configuration page or making an API call.

In Octopus Deploy versions 3.0.19 to 2019.7.2, when a web request proxy is configured, an authenticated user (in certain limited circumstances) could trigger a deployment that writes the web request proxy password to the deployment log in cleartext. This is fixed in 2019.7.3. The fix was back-ported to LTS 2019.6.5 as well as LTS 2019.3.7.

In Octopus Deploy 2019.1.0 through 2019.3.1 and 2019.4.0 through 2019.4.5, an authenticated user with the VariableViewUnscoped or VariableEditUnscoped permission scoped to a specific project could view or edit unscoped variables from a different project. (These permissions are only used in custom User Roles and do not affect built in User Roles.)

Jenkins OctopusDeploy Plugin stores credentials unencrypted in its global configuration file on the Jenkins master where they can be viewed by users with access to the master file system.

A server-side request forgery vulnerability exists in Jenkins OctopusDeploy Plugin 1.8.1 and earlier in OctopusDeployPlugin.java that allows attackers with Overall/Read permission to have Jenkins connect to an attacker-specified URL and obtain the HTTP response code if successful, and exception error message otherwise.

An Information Exposure issue in the Terraform deployment step in Octopus Deploy before 2019.1.8 (and before 2018.10.4 LTS) allows remote authenticated users to view sensitive Terraform output variables via log files.

In Octopus Deploy 2018.8.0 through 2018.9.x before 2018.9.1, an authenticated user with permission to modify deployment processes could upload a maliciously crafted YAML configuration, potentially allowing for remote execution of arbitrary code, running in the same context as the Octopus Server (for self-hosted installations by default, SYSTEM).

In Octopus Deploy 3.0 onwards (before 2018.6.7), an authenticated user with incorrect permissions may be able to create Accounts under the Infrastructure menu.

In Octopus Deploy version 2018.5.1 to 2018.5.7, a user with Task View is able to view a password for a Service Fabric Cluster, when the Service Fabric Cluster target is configured in Azure Active Directory security mode and a deployment is executed with OctopusPrintVariables set to True. This is fixed in 2018.6.0.
