Guest access expansion via extension endpoints

Published Aug 2, 2023 · Updated Oct 11, 2024

Incorrect privilege assignment in Octopus Server allows remote authenticated users to interact with extension endpoints. Octopus Deploy has not published the affected endpoint names or the authorization operation that incorrectly grants guest access. A low-privileged guest account and additional user interaction are required; the exposed functionality can affect confidentiality, integrity, and availability, but the precise actions remain undisclosed.
