A vulnerability in Elastic Container Registry (ECR) Public could have allowed a
malicious actor to delete, update, or create ECR Public images, layers, or tags
in registries and repositories belonging to any other AWS account, by abusing
undocumented API calls. A malicious actor could have exploited this to delete
any or all images in the Amazon ECR Public Gallery or update the content of any
existing image to inject malicious code on any machine that would pull and run it.
