Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading? Replace

          if .request.requestKind.kind == "Secret" {
            del(.request.object.data)
            .request.object.data.redacted = "REDACTED"
            del(.request.oldObject.data)
            .request.oldObject.data.redacted = "REDACTED"
          }

In the vector "audit-files-json-parser-and-redaction" step with

          if .request.requestKind.kind == "Secret" {
            # Redact the secret data
            del(.request.object.data)
            .request.object.data.redacted = "REDACTED"
            del(.request.oldObject.data)
            .request.oldObject.data.redacted = "REDACTED"
            # Remove the previously set secret data - Not bothering to parse it as this annotation shouldn't ever be needed
            del(.request.object.metadata.annotations.["kubectl.kubernetes.io/last-applied-configuration"])
            del(.request.oldObject.metadata.annotations.["kubectl.kubernetes.io/last-applied-configuration"])
          }
