The value is written verbatim into the HAProxy configuration generated on the amphora, and thus an authenticated project member who owns a TLS-enabled load balancer can embed a newline and inject arbitrary HAProxy configuration directives. Only deployments using the Amphora provider are affected.","state":0,"publishedAt":"2026-09-21T20:13:35.557+00:00","modifiedAt":"2026-09-24T22:41:15.736+00:00","affected":[{"ecosystem":"Vendor product","name":"Octavia","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Octavia\",\n                    \"repo\": \"https://opendev.org/openstack/octavia\",\n                    \"vendor\": \"OpenStack\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"16.1.0\",\n                            \"status\": \"affected\",\n                            \"version\": \"6.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"17.0.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"17.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"18.0.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"18.0.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\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:H/SI:H/SA:H","score":9.4,"severity":"CRITICAL"}],"references":["https://bugs.launchpad.net/octavia/+bug/2162101","https://bugs.launchpad.net/octavia/+bug/2167565","https://bugs.debian.org/1148175","https://opendev.org/openstack/octavia/commit/cad62902e4984a46ad80cbfa943e90006d8d599d","https://security.openstack.org/ossa/OSSA-2026-039.html","https://openwall.com/lists/oss-security/2026/09/21/6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-94572","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-94572","identifiers":["CVE-2026-94572"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
