Cisco PSIRT openVuln API

The Cisco Product Security Incident Response Team (PSIRT) openVuln API is Cisco's machine-readable vulnerability disclosure service. It lets security teams query Cisco security advisories by CVE, advisory ID, severity, publication date, affected product or specific IOS/IOS-XE release, and returns CVRF and OVAL content alongside JSON. It is one of the few Cisco surfaces with a genuinely public, fetchable OpenAPI 3.0.3 document, published in the CiscoPSIRT GitHub organization.

Cisco PSIRT openVuln API publishes 3 APIs on the APIs.io network: Current Endpoints API, Obsolete Endpoints API, and Sunset Endpoints API. Tagged areas include Security, Vulnerability Management, Threat Intelligence, Disclosure, and Compliance.

Cisco PSIRT openVuln API’s developer surface includes authentication, developer portal, documentation, API reference, CLI, getting-started guide, FAQ, and 33 more developer resources.
