Types

type EPSSRecord

type EPSSRecord struct {
	CVE        string  `json:"cve"`
	EPSS       float64 `json:"epss"`
	Percentile float64 `json:"percentile"`
	Date       string  `json:"date,omitempty"` // Added during processing
}

EPSSRecord represents a single EPSS score entry.

type Provider

type Provider struct {
	// contains filtered or unexported fields
}

Provider implements the EPSS provider.

func NewProvider

func NewProvider(cfg provider.Config) (*Provider, error)

NewProvider creates a new EPSS provider.

func (p *Provider) FetchAll(ctx context.Context) error

FetchAll downloads and processes the EPSS CSV.

func (*Provider) FetchIncremental

func (p *Provider) MetadataPath() string

MetadataPath returns the path to metadata.json.

func (*Provider) Name

func (p *Provider) Name() string
