In Octopus Deploy versions 2018.8.4 to 2019.7.6, when a web request proxy is configured, an authenticated user (in certain limited special-characters circumstances) could trigger a deployment that writes the web request proxy password to the deployment log in cleartext.

In Octopus Tentacle versions 3.0.8 to 5.0.0, when a web request proxy is configured, an authenticated user (in certain limited OctopusPrintVariables circumstances) could trigger a deployment that writes the web request proxy password to the deployment log in cleartext.
