AWS Security Bulletins
Amazon Web Services publishes security bulletins for issues affecting AWS services, open-source projects it maintains and cross-industry vulnerabilities that touch cloud workloads. For teams running on AWS, a bulletin is the authoritative word on whether the platform is affected and what customers must patch themselves.
CSIRTS.com ingests AWS Security Bulletins every 3 hours, normalizes each advisory into a common schema and cross-references every CVE against the CISA KEV catalog and public exploit datasets. Publishes security bulletins for AWS services and cloud workloads. Also available via RSS, JSON API and the MCP server.
