{"cve":"CVE-2026-41184","nvd":{"published":"2026-05-28T17:16:22.270","modified":"2026-10-26T13:10:00.140","status":"Analyzed","description":"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.","cvss_v4":{"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":6.0},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-532"],"references":["https://github.com/projectcalico/calico/pull/12502","https://github.com/projectcalico/calico/pull/12526","https://github.com/projectcalico/calico/pull/12527","https://www.tigera.io/security-bulletins/tta-2026-001/"],"products":["tigera:calico"],"source":"nvd","synced_at":"2026-10-26T13:39:24.642594360+00:00"},"epss":{"cve":"CVE-2026-41184","score":0.00504,"percentile":0.4282,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-9p7w-w5q6-mxj3","url":"https://osv.dev/vulnerability/GHSA-9p7w-w5q6-mxj3","summary":"Calico Inserts Sensitive Information into Log File","modified":"2026-07-07T16:11:05.825939673Z","packages":[{"ecosystem":"Go","name":"github.com/projectcalico/calico","purl":"pkg:golang/github.com/projectcalico/calico","ranges":[">=2.0.0 <3.31.6"],"fixed":["3.31.6"]},{"ecosystem":"Go","name":"github.com/projectcalico/calico","purl":"pkg:golang/github.com/projectcalico/calico","ranges":["<1.11.0-cni-plugin.0.20260417001138-cd73bc2cea0f"],"fixed":["1.11.0-cni-plugin.0.20260417001138-cd73bc2cea0f"]}]},{"id":"GO-2026-5888","url":"https://osv.dev/vulnerability/GO-2026-5888","summary":"Calico Inserts Sensitive Information into Log File in github.com/projectcalico/calico","modified":"2026-07-07T16:01:31.227978521Z","packages":[{"ecosystem":"Go","name":"github.com/projectcalico/calico","purl":"pkg:golang/github.com/projectcalico/calico","ranges":["<1.11.0-cni-plugin.0.20260417001138-cd73bc2cea0f"],"fixed":["1.11.0-cni-plugin.0.20260417001138-cd73bc2cea0f"]},{"ecosystem":"Go","name":"github.com/projectcalico/calico/v3","purl":"pkg:golang/github.com/projectcalico/calico/v3","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
