Struct EpssSource 

pub struct EpssSource { /* private fields */ }

EPSS data source.

Provides exploit probability scores for CVEs. These scores help prioritize vulnerabilities based on likelihood of exploitation.

Implementations

impl EpssSource

pub fn new() -> Self

Create a new EPSS source.

pub async fn fetch_scores( &self, cve_ids: &[&str], ) -> Result<HashMap<String, EpssScore>>

Fetch EPSS scores for specific CVE IDs.

Arguments

• cve_ids - List of CVE IDs to look up (e.g., [“CVE-2024-1234”, “CVE-2024-5678”])

Returns

A map of CVE ID to EPSS score data.

pub async fn fetch_score(&self, cve_id: &str) -> Result<Option<EpssScore>>

Fetch a single CVE’s EPSS score.

pub async fn fetch_high_risk( &self, min_epss: f64, limit: Option<u32>, ) -> Result<Vec<EpssScore>>

Fetch all CVEs with EPSS score above a threshold.

Arguments

• min_epss - Minimum EPSS probability (0.0 - 1.0)
• limit - Maximum number of results (default: 100)

pub async fn fetch_top_percentile( &self, min_percentile: f64, limit: Option<u32>, ) -> Result<Vec<EpssScore>>

Fetch CVEs with EPSS percentile above a threshold.

Arguments

• min_percentile - Minimum percentile (0.0 - 1.0, e.g., 0.95 for top 5%)
• limit - Maximum number of results

pub async fn fetch_scores_batch( &self, cve_ids: &[String], batch_size: usize, ) -> Result<HashMap<String, EpssScore>>

Fetch EPSS scores in batches for a large list of CVEs.

The API can handle many CVEs in a single request, but we batch to avoid URL length limits.

Trait Implementations

impl Default for EpssSource

fn default() -> Self

Returns the “default value” for a type.
