AWS acm documentation change

Service: acm · 2026-04-10 · Documentation medium

File: acm/latest/userguide/dochistory.md

Summary

Added two document history entries: 1) ECDSA Key Usage exception for certificate reimport (compliance with RFC 5480), 2) SearchCertificates documentation update.

Security assessment

The ECDSA Key Usage exception change addresses a compliance issue with RFC 5480 standards for certificate validation, which has security implications for certificate handling. However, this appears to be a standards compliance update rather than fixing a specific security vulnerability. The SearchCertificates entry is a routine documentation update.
