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 35 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cisco-psirt: open an issue to ask a question, or submit a pull request to add artifacts.
