This could result in a token issued from a suitably configured non legitimate issuer being accepted as a token belonging to a service account from a legitimate trusted issuer. Exploitation requires a service account with at least one OIDC identity configured. An attacker would also need to know or guess some details of that identity in order to be in a position to attempt exploitation.","state":0,"publishedAt":"2026-10-27T10:28:11.007+00:00","modifiedAt":"2026-10-27T10:28:11.007+00:00","affected":[{"ecosystem":"Vendor product","name":"Octopus Server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Octopus Deploy\",\n                    \"product\": \"Octopus Server\",\n                    \"platforms\": [\n                        \"Windows\",\n                        \"Linux\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2024.1.0\",\n                            \"lessThan\": \"2026.1.11781\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2026.2.0\",\n                            \"lessThan\": \"2026.2.13438\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2026.3.0\",\n                            \"lessThan\": \"2026.3.15816\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://advisories.octopus.com/post/2026/sa2026-15"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116870","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116870","identifiers":["CVE-2026-116870"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
