CVE-2026-12702Network attack vector

Unauthorized deployments via unchecked project trigger actions

Published Jul 24, 2026 · Updated Jul 24, 2026

Incorrect authorization in Octopus Server allows remote authenticated users to trigger deployments for projects they cannot control. Project trigger actions lack sufficient authorization checks, but Octopus Deploy has not disclosed the affected handler or exact permission comparison. Exploitation requires a high-privilege authenticated account and changes deployment state without reported confidentiality or availability impact.
