Affected packages

Description
Impact
_What kind of vulnerability is it? Who is impacted?_
If the "full-elastic-stack" example vector configuration was used for a real cluster, the previous values of kubernetes secrets would have been disclosed in the audit messages.
Patches
_Has the problem been patched? What versions should users upgrade to?_
The example has been updated to fix this in commit 9df8886b4819409f566233adc7c3b7a43a4096ba
Workarounds
_Is there a way for users to fix or remediate the vulnerability without upgrading?_
Replace
```yaml
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
```yaml
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"])
}
```
