{"id":"CVE-2026-55225","summary":"Strimzi: Cross-namespace privilege escalation via `Kafka.spec.entityOperator`","details":"Strimzi provides a way to run an Apache Kafka cluster on Kubernetes or OpenShift in various deployment configurations. In Strimzi 1.0.0 and earlier, an attacker who can create a Kafka custom resource can set Kafka.spec.entityOperator watchedNamespace to a target namespace, causing the Cluster Operator to create a Role with full Secret CRUD permissions there and bind it to the Entity Operator ServiceAccount in the attacker's namespace. The attacker can mint a token for that ServiceAccount and read or write Secrets in any target namespace where the Cluster Operator has been granted permissions, regardless of STRIMZI_NAMESPACE. This issue is fixed in versions 1.0.1 and 1.1.0.","aliases":["GHSA-mw9r-p8xp-wx96"],"modified":"2026-09-16T11:30:46.176936009Z","published":"2026-09-15T17:15:51.236Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55225.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-441"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55225.json"},{"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":"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/strimzi/strimzi-kafka-operator/security/advisories/GHSA-mw9r-p8xp-wx96"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55225"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/strimzi/strimzi-kafka-operator","events":[{"introduced":"0"},{"fixed":"833dbbd4fc745678f11ad96ed66571704cd73cd0"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"1.0.1"}]}}],"versions":["1.0.1-rc1","1.0.0-rc2","1.0.0","1.0.0-rc1","0.1.0-rc3","0.1.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55225.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
