Fetches detailed GitHub Security Advisory (GHSA) data including CVSS scores, CVE IDs, severity, and affected package versions for a given GHSA identifier

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability signaldesk-ai-github-security-advisory-lookup-f9312e6f
```

Example prompt: Can you pull up the full GitHub security advisory for GHSA-vh95-rmgr-6w4m — I need the CVSS score, severity, CVE ID, and which package versions are affected?

## When to prefer this

Use this endpoint when you need structured, machine-readable details about a specific known GitHub Security Advisory by its GHSA identifier — including CVSS scoring, affected package versions, and patch guidance. Prefer this over manual GitHub browsing when building automated vulnerability triage pipelines, enriching security tickets, or checking whether a specific dependency version is affected. Best suited for single advisory lookups by GHSA ID; not designed for bulk scanning or searching advisories by package name.

## Known failure modes

- Invalid GHSA ID format (must match ^GHSA-[a-z0-9]{4}-[a-z0-9]{4}-[a-z0-9]{4}$) returns a 4xx error
- GHSA ID not found in GitHub advisory database returns empty or 404 response
- GitHub public API anonymous quota exhausted causes temporary rate-limit failure
- Network timeout or upstream GitHub API unavailability
- Stale cached data if the advisory was recently updated (cache expires ~1 hour after fetch)

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the GHSA ID, linked CVE ID, summary description, severity level (e.g. medium/high/critical), CVSS score and vector string, a list of affected packages with their ecosystems and vulnerable version ranges, the first patched version for each, and source metadata including fetch timestamp and expiry.
