{"id":"CVE-2026-41184","summary":"ServiceAccount token disclosure via install-cni container logs","details":"In Calico, the install-cni init container logs the rendered CNI configuration to standard output. 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.","aliases":["GHSA-9p7w-w5q6-mxj3","GO-2026-5888"],"modified":"2026-07-08T08:13:12.693281766Z","published":"2026-05-28T15:47:42.173Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41184.json","cwe_ids":["CWE-532"],"cna_assigner":"Tigera"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41184.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41184"},{"type":"ADVISORY","url":"https://www.tigera.io/security-bulletins/tta-2026-001/"},{"type":"FIX","url":"https://github.com/projectcalico/calico/pull/12502"},{"type":"FIX","url":"https://github.com/projectcalico/calico/pull/12526"},{"type":"FIX","url":"https://github.com/projectcalico/calico/pull/12527"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/projectcalico/calico","events":[{"introduced":"0"},{"fixed":"eb1cf57823a1dd8d25c48b82fd023ea9e3e17996"},{"introduced":"a86e41d021c4c60e1f73d8dce396fe249d708cc7"},{"fixed":"1be7791d130f7756981f67cce23b260be0330aa0"}],"database_specific":{"cpe":["cpe:2.3:a:tigera:calico:*:*:*:*:open_source:*:*:*","cpe:2.3:a:tigera:calico:*:*:*:*:enterprise:*:*:*"],"source":"CPE_RANGE","extracted_events":[{"introduced":"0"},{"fixed":"3.32.0"},{"introduced":"3.22.0"},{"fixed":"3.22.3"}]}}],"versions":["v3.32.0-0.dev","v3.31.0-0.dev","v3.30.0-0.dev","v3.29.0-0.dev","v3.28.0-0.dev","v3.27.0-0.dev","v3.25.0-0.dev","v3.22.3-0.dev","v3.24.0-0.dev","v3.18.5-calico","v3.18.5","v3.17.5-calico","v3.17.5","v3.18.1-calico","v3.18.1","v3.16.5-calico","v3.16.5","v3.16.0-calico","v3.16.0","v3.11.1-calico","v3.11.1","v3.9.4-calico","v3.9.4","v3.8.5-calico","v3.8.5","v3.10.2-calico","v3.10.2","v3.10.0-calico","v3.10.0","v3.9.0-calico","v3.9.0","v3.3.7-calico","v3.3.7","v3.2.8-calico","v3.2.8","v3.1.7-calico","v3.1.7","v3.0.12-calico","v3.0.12","v3.2.0-calico","v3.2.0","v3.0.1-calico","v3.0.1","v3.0.0-calico","v3.0.0","v2.6.2-calico","v2.6.2","v3.0.0-alpha1-rc1-calico","v3.0.0-alpha1-rc1","v2.6.0-calico","v2.6.0","v2.6.0-rc2-calico","v2.6.0-rc2","v2.6.0-rc1-calico","v2.6.0-rc1","v2.5.0-calico","v2.5.0","v2.5.0-rc2-calico","v2.5.0-rc2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41184.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
