CVE-2026-54680: Logging operator automates the deployment and configuration of Kubernetes logging pipelines. Prior to 6.6.0, the Fluentd configuration renderer FluentRender in pkg/sdk/logging/mode

criticalCVSS 9.9CVE-2026-54680

Logging operator automates the deployment and configuration of Kubernetes logging pipelines. 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.
