Overview

Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm when storing encrypted data keys in an instruction file. An attacker with write access to the S3 bucket can manipulate encrypted data keys to cause decryption to unintended plaintext by introducing a new encrypted data key.

Note: Version 3.2.0 introduces key commitment to ensure the encrypted data key is cryptographically bound to the ciphertext in read messages. This is only enforced for writes as well in version 4.0.0.
