The Cisco PSIRT openVuln API is a RESTful API that allows customers to obtain Cisco security vulnerability information in different machine-consumable formats. It supports industrywide security standards such as:

• OASIS Common Security Advisory Framework (CSAF)
• Common Vulnerability and Exposure (CVE) identifiers
• Common Weakness Enumerator (CWE)
• Common Vulnerability Scoring System (CVSS)

NOTE: CSAF is a specification for structured machine-readable vulnerability-related advisories and further refine those standards over time.

Please refer to the openVuln API documentation and learn how to access it at: https://developer.cisco.com/psirt

NOTE: The openVuln API is open to registered Cisco customers and partners.

The open-source community-supported Python-based API client (openVulnQuery) can be obtained from: https://github.com/CiscoPSIRT/openVulnQuery
