As a result, a user who can create `Flow` resources can inject Fluentd configuration by providing values that contain newlines.\n\nIn the confirmed path, a value in `record_transformer.records` can close the current `` / `` block and add a new `` block. By specifying Fluentd's core `@type exec` plugin in that injected block, an attacker can execute arbitrary commands inside the Fluentd aggregator.\n\n### Details\n\nThe issue is in `FluentRender` in `pkg/sdk/logging/model/render/fluent.go`.\n\nhttps://github.com/kube-logging/logging-operator/blob/98275d2984aa8d731c4c975b8006aa433fc7bafa/pkg/sdk/logging/model/render/fluent.go#L60-L87\n\nEach parameter is rendered as `key value`, but values are not quoted, and newlines or characters such as `` are not rejected. In addition, `indentedf` builds the string with `fmt.Sprintf` and then splits it on `\\n`, so newlines inside CRD values become new lines in the generated Fluentd configuration.\n\nOne input source is `record_transformer.records`. `ToDirective` passe","public_affected_ranges":["< 0.0.0-20260608145523-cf437d7f1e05"]}],"null_published_at":"2026-11-03T10:03:26.565Z","source_updated_at":"2026-07-29T17:01:29.000Z","source_disclosed_at":"2026-07-29T17:01:29.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T09:58:49.818Z"}],"next_cursor":null,"snapshot_revision":"42594"}
