CVE-2022-2259Network attack vector

Authenticated worker-pool disclosure via missing permission check

Published Mar 13, 2023 · Updated Mar 3, 2025

Improper access control in Octopus Server allows remote authenticated users to view worker pools without assigned permissions. Octopus Deploy has not published the affected request handler or the authorization operation that fails to enforce worker-pool view permission. An authenticated account is required; the disclosed impact is read-only exposure of worker-pool information, with no reported modification or service interruption.
