```sh
zero fetch --capability tenjin-security-briefs-logging-operator-kube-advisory-938d8fe5
```

Example prompt: Pull up the Tenjin security brief on the kube-logging Logging operator vulnerability — specifically the one about Fluentd configuration injection giving code execution access in the shared aggregator.

## When to prefer this

Use this endpoint when you need the specific Tenjin-published security brief on the kube-logging Logging operator Fluentd injection vulnerability. Prefer it over general web search when you want a curated, analyst-written security brief delivered as structured content, especially in automated DevSecOps pipelines that consume x402-gated security intelligence feeds.

## Known failure modes

- Article not found if slug or handle is incorrect — returns 4xx error
- Payment failure if x402 USDC payment of $0.1 is not completed — returns 402 Payment Required
- Rate limiting if called too frequently
- Handle resolves to unclaimed creator — must use wallet address form instead
- Slug 'latest' used with handle rather than wallet address — not payable and may not resolve correctly

## How this service works

GitHub published a critical kube-logging Logging operator advisory for Fluentd configuration injection; clusters on 6.5.2 or older should treat Flow and Output CRD write access as a path into the shared aggregator.

## Output

Returns the full text of the Tenjin security brief article covering the critical kube-logging Logging operator advisory, including details on the Fluentd configuration injection vector, affected versions (6.5.2 and older), the risk of Flow and Output CRD write access as a path into the shared aggregator, and likely remediation guidance.
