How this service works
CISA's Known Exploited Vulnerabilities catalog (public JSON). With cveId: whether that CVE is on the list, with vendor, product, date added, federal due date, required action and ransomware-use flag. Without it: catalog size, release date and the newest additions (up to 50). Listing means exploitation was reported, not a risk score.
Output
When a cveId is provided: a JSON object with the CVE's KEV status (listed or not), vendor, product, date added to the catalog, federal remediation due date, CISA-mandated required action, and a ransomware-use flag. Without a cveId: the total catalog size, the catalog release/last-updated date, and the most recent additions (up to the requested limit, default 10, max 50).
Example use cases
Patch prioritization for security team
“We're triaging our vulnerability backlog — can you check if CVE-2021-44228 (Log4Shell) is on the CISA KEV list and tell me the required action and federal due date so we know how urgently we need to patch it?”
Ransomware risk screening
“I need to know if CVE-2022-30190 (Follina) is flagged as being used in ransomware campaigns by CISA's Known Exploited Vulnerabilities catalog — include the vendor and product details if it's listed.”
Daily KEV catalog briefing
“Pull the 20 most recently added vulnerabilities from the CISA Known Exploited Vulnerabilities catalog so I can brief my team on what CISA has flagged for exploitation this week.”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/cisa-known-exploits?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine whether a specific CVE has confirmed real-world exploitation as recognized by CISA, or to retrieve federal compliance deadlines (due dates) for patching. Prefer this over generic CVSS/NVD lookups when the question is 'has this been exploited in the wild and does it require federal remediation?' rather than 'what is the theoretical severity score?' It is ideal for compliance-driven patch prioritization and ransomware risk screening.
Side effects
- CVE ID not found in KEV catalog — returns a not-listed result, not an error
- Invalid CVE ID format may return an error or empty result
- limit parameter outside 1–50 range may be clamped or return an error
- Upstream CISA JSON unavailable causes service failure
- Network timeout from Cloudflare Worker if CISA source is slow
