{"id":"CVE-2026-55226","aliases":["GHSA-r427-j2h7-wv3m"],"url":"https://o3.security/vulnerability/CVE-2026-55226","summary":"Strimzi: Unrestricted access to all Secrets within namespace watched by the Topic operator","details":"### Impact\n\nWhen only the Topic or only the User operators are deployed as part of the Entity Operator in the `Kafka` custom resource, the RBAC rights are not following the principle of least-privilege and the Entity Operator ServiceAccount still has access rights corresponding to both operators. That might allow the ServiceAccount to access `KafkaUser` custom resources and Secrets when the User operator is not deployed and access `KafkaTopic` custom resources when the Topic operator is not deployed.\n\n### Patches\n\nThe issue is fixed in Strimzi 1.0.1 and 1.1.0.\n\n### Workarounds\n\nThere is no workaround for this issue.","published":"2026-09-15T17:14:21.491Z","modified":"2026-10-21T10:20:08.090523985Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N"},"epss":{"score":0.00183,"percentile":0.08177,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"io.strimzi:strimzi","fixedVersion":"1.0.1"}],"fix":{"url":"https://github.com/strimzi/strimzi-kafka-operator/commit/b3bfeffcc30754c3e62e6f4afd8a76942cac440d","label":"strimzi/strimzi-kafka-operator@b3bfeff"},"references":[{"type":"WEB","url":"https://github.com/strimzi/strimzi-kafka-operator/releases/tag/1.0.1"},{"type":"WEB","url":"https://github.com/strimzi/strimzi-kafka-operator/releases/tag/1.1.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55226.json"},{"type":"ADVISORY","url":"https://github.com/strimzi/strimzi-kafka-operator/security/advisories/GHSA-r427-j2h7-wv3m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55226"},{"type":"FIX","url":"https://github.com/strimzi/strimzi-kafka-operator/commit/b3bfeffcc30754c3e62e6f4afd8a76942cac440d"},{"type":"FIX","url":"https://github.com/strimzi/strimzi-kafka-operator/commit/f6c5207ba7ec89b46ce6720b8638d647e556a261"},{"type":"FIX","url":"https://github.com/strimzi/strimzi-kafka-operator/pull/12844"},{"type":"PACKAGE","url":"https://github.com/strimzi/strimzi-kafka-operator"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T10:20:08.090523985Z"}}
