ICYMI: August 2026 @AWS Security

August 2026 AWS Security Blog digest summarizing 20+ posts, 23 security bulletins, and 17 new code samples across identity, data protection, AI security, threat detection, infrastructure, and governance. Notable security coverage includes multiple high-impact vulnerability classes (RCE, Java deserialization, path traversal, Zip Slip, SSRF, stored XSS, privilege escalation, and supply-chain/agent-tool authorization flaws) with a recurring theme of insufficient authorization/input validation at AI agent boundaries; patches are available and prompt upgrading is recommended.
