GitHub Actions – OIDC integration with AWS no longer requires pinning of intermediate TLS certificates

GitHub Actions – OpenId Connect (OIDC) integration with AWS is now optimized to avoid pinning any intermediary certificate thumbprints.

While configuring GitHub as an OIDC IdP (ID Provider), AWS now secures communication by trusting GitHub Actions’s trusted root certificate authorities (CAs) instead of using a certificate thumbprint to verify GitHub’s IdP server certificate.
This will address and avoid any issues caused due to pinning certificate thumbprints while authenticating from GitHub to AWS using OIDC. No action is needed for GitHub customers.
