### Recipe 8 - CVSS Policy with Fix Available
This policy is designed to match packages in a specific repository (```acme-repo-one```) that have ```high``` or ```critical```vulnerabilities that also have a ```Fix``` available, excluding specific ```known CVEs```.
Download the ```policy.rego``` and create the associated ```payload.json``` with the below command:
```
wget https://raw.githubusercontent.com/cloudsmith-io/rego-recipes/refs/heads/main/recipe-8/policy.rego
escaped_policy=$(jq -Rs . < policy.rego)
cat <<EOF > payload.json
{
"name": "CVSS Policy with Fix Available",
"description": "Match packages that have high or critical CVEs where a fix is available",
"rego": $escaped_policy,
"enabled": true,
"is_terminal": false,
"precedence": 8
}
EOF
```

To demonstrate this policy, you can use the ```requests``` Python package, which has a known vulnerability with a high CVSS score.
