Name of the Vulnerable Software and Affected Versions AWS SDK for Ruby versions prior to 1.208.0

Description A missing cryptographic key commitment in the AWS SDK for Ruby could allow a user with write access to an S3 bucket to introduce a new encryption data key (EDK) that decrypts to different plaintext. This is possible when the encrypted data key is stored in an instruction file instead of S3’s metadata record.

Recommendations Upgrade AWS SDK for Ruby to version 1.208.0 or later.
