Prior to 6.6.0, the Fluentd configuration renderer FluentRender in pkg/sdk/logging/model/render/fluent.go writes CRD strings such as Flow record_transformer.records values directly into fluent.conf without escaping, allowing a user who can create Flow resources to inject a Fluentd <match **> block using @type exec and execute arbitrary commands inside the Fluentd aggregator. This issue is fixed in version 6.6.0.","published":"2026-07-29T16:57:16.913Z","modified":"2026-09-12T03:30:48.875565985Z","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.00525,"percentile":0.42905,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/kube-logging/logging-operator","fixedVersion":"0.0.0-20260608145523-cf437d7f1e05"}],"fix":{"url":"https://github.com/kube-logging/logging-operator/commit/cf437d7f1e056c78740bf5716ac8bdebcf002425","label":"kube-logging/logging-operator@cf437d7"},"references":[{"type":"WEB","url":"https://github.com/kube-logging/logging-operator/releases/tag/6.6.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54680.json"},{"type":"ADVISORY","url":"https://github.com/kube-logging/logging-operator/security/advisories/GHSA-mjqf-28ph-426h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54680"},{"type":"FIX","url":"https://github.com/kube-logging/logging-operator/commit/cf437d7f1e056c78740bf5716ac8bdebcf002425"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-12T03:30:48.875565985Z"}}
