**APIs profiled:** 3

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.
