When the configuration template uses the __SERVICEACCOUNT_TOKEN__ placeholder (Canal/Flannel-Calico deployments), the installer substitutes the live Kubernetes ServiceAccount bearer token before logging, exposing the token to any authenticated user with pods/log permission in the namespace with calico-node. The token holds patch privileges on pods/status, enabling annotation-based attacks against cluster workloads. The default kubeconfig-based authentication path is not affected. This is a direct regression of TTA-2018-001.","state":0,"publishedAt":"2026-05-28T15:47:42.173+00:00","modifiedAt":"2026-05-28T17:04:36.059+00:00","affected":[{"ecosystem":"Vendor product","name":"cni-plugin","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Tigera\",\n                    \"product\": \"Calico\",\n                    \"packageName\": \"cni-plugin\",\n                    \"versions\": [\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"3.32.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"3.31.6\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:L/SI:L/SA:L","score":6,"severity":"MEDIUM"}],"references":["https://github.com/projectcalico/calico/pull/12502","https://github.com/projectcalico/calico/pull/12527","https://github.com/projectcalico/calico/pull/12526","https://www.tigera.io/security-bulletins/tta-2026-001/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-41184","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-41184","identifiers":["CVE-2026-41184"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
