CVE-2022-2508Network attack vector

Resource-existence disclosure via verbose validation errors

Published Oct 27, 2022 · Updated May 7, 2025

Information exposure in Octopus Deploy Octopus Server allows remote attackers to discover inaccessible resources through verbose error responses. Resource validation emits existence-dependent errors for objects in spaces outside the requester's authorized scope. The consequence is limited to confirming whether a named resource exists in an inaccessible space; resource contents are not reported.
