Description

Missing cryptographic key commitment in the Amazon S3 Encryption Client for Go may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record. To mitigate this issue, upgrade Amazon S3 Encryption Client for Go to version 4.0 or later.

aws/amazon-s3-encryption-client-go

The Amazon S3 Encryption Client is a client-side encryption library that enables you to encrypt an object locally to ensure its security before passing it to Amazon Simple Storage Service (Amazon S3).
