Censor nested YAML string values.
addYAMLValuesToCensor registers only root-level strings. Nested YAML objects decode as map[string]interface{} and sequences as []interface{}, so nested kubeconfig tokens are omitted. The shared censor protects CI log output and the verbose JSON artifact, but full-payload censoring cannot redact a separately emitted scalar. Recursively walk mappings and sequences, and add a nested-token test.
Proposed fix
func addYAMLValuesToCensor(payload []byte, censor *secrets.DynamicCensor) {
- var data map[string]interface{}
- if err := yaml.Unmarshal(payload, &data); err != nil || data == nil {
+ var data interface{}
+ if err := yaml.Unmarshal(payload, &data); err != nil {
return
}
- for _, v := range data {
- if s, ok := v.(string); ok && s != "" {
- censor.AddSecrets(s)
+
+ var addValue func(interface{})
+ addValue = func(value interface{}) {
+ switch value := value.(type) {
+ case string:
+ if value != "" {
+ censor.AddSecrets(value)
+ }

When a GSM secret contains a YAML mapping, the sidecar currently censors only the whole file content as a single pattern. Values extracted individually via yq, awk, sed, or cut bypass censoring. Parse the payload as YAML after adding the whole-file pattern, and add each individual string value as a separate censor entry. Non-YAML payloads are silently ignored so plain-text secrets continue to work. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

When a GSM secret contains a YAML mapping, the sidecar currently censors only the whole file content as a single pattern. Values extracted individually via yq, awk, sed, or cut bypass censoring.
Parse the payload as YAML after adding the whole-file pattern, and add each individual string value as a separate censor entry. Non-YAML payloads are silently ignored so plain-text secrets continue to work.
Updates
csi_secretsto censor individual non-empty string values from YAML-mapped GSM secrets in CI logs. The complete secret payload remains censored.Invalid YAML, non-string values, and empty values are ignored. Plain-text secrets continue to work. Adds table-driven tests for these cases.
