AWS AWSEC2 documentation change

Service: AWSEC2 · 2025-04-18 · Documentation low

File: AWSEC2/latest/UserGuide/ami-last-launched-time.md

Summary

Updated documentation for viewing AMI last launched time with clearer CLI/PowerShell examples and workflow steps. Added explicit verification notes about AMI ownership requirements.

Security assessment

Changes emphasize verifying AMI ownership to view attributes, which relates to access control but doesn't address a specific vulnerability. The updates are documentation improvements rather than security fixes or new security features.
