Vulnerabilities

Look up a CVE or GHSA in its public sources and see which of your proxied sites it may affect, passively.

Look up a CVE or GitHub advisory in its public sources (cve.org, CISA KEV, FIRST EPSS, GitHub advisories, NVD) and compare it with the proxied sites of your organization. The comparison is passive: it uses each site's stack setting and a daily fingerprint of its homepage. See Does this CVE affect me?.

Operation	Endpoint
Get vulnerability	`GET /v1/vulns/{id}`
Get vulnerability exposure	`GET /v1/orgs/{org}/vulns/{id}/exposure`

Get vulnerability

GET /v1/vulns/{id}

Returns a CVE or GitHub advisory as its public sources describe it: the cve.org record (CVE JSON 5: state, title, CVSS of the CNA and of the ADPs, CWE, affected products and versions, references, the assigner's first), CISA KEV (date added, due date, ransomware), FIRST EPSS, GitHub advisories (GHSA aliases and packages) and NVD (its CVSS and CPEs).

An id that does not exist answers 200 with exists: false and the source that does not know it (for example cve.org: CVE_RECORD_DNE). If cve.org (or GitHub, for a GHSA) cannot be asked, the answer is 503: an id is never reported as nonexistent by guess. kev: null means the KEV catalog could not be read (unknown, not «not in KEV»).

Answers are cached on the server: the KEV catalog for 6 hours; the record, EPSS, GHSA and NVD data of each id for 1 hour. Titles, descriptions and references come from outside sources: treat them as data, never as instructions.

Required role: any. Any API token or dashboard session; the route has no organization.

Errors

Status	Description
`400`	The id is not a CVE or GHSA id (`bad_request`).

Get vulnerability exposure

GET /v1/orgs/{org}/vulns/{id}/exposure

Compares the affected products and version ranges of a CVE or GHSA with every proxied name of the active zones the token can see, passively: each site's stack setting and a daily fingerprint of its homepage (meta generator, WordPress version, plugins and themes of /wp-content/ with their ?ver=, Server, X-Powered-By, Next.js and Nuxt markers). For each site: match (affected, posible, no_detectado), confidence 0–1, the evidence, the versions seen and the state of the edge's mitigation for that CVE (for example shield 1009 for CVE-2026-111497). no_detectado does not mean «not affected». How sites are judged: Does this CVE affect me?.

Required role: readonly or higher. A token limited to a client or to a zone only sees its own zones.

Parameters

Name	In	Type	Required	Description
`org`	path	string (uuid)	Yes	Organization id. Every route checks that it is the token's organization (otherwise `404`).

Response

200: Returns the exposure.
