Overview
aws-encryption-sdk-cli is a This command line tool can be used to encrypt and decrypt files and directories using the AWS Encryption SDK.
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature. The ESDK uses AES-GCM encryption and all plaintext is verified before being released to a caller. There is no impact on the integrity of the ciphertext or decrypted plaintext, however some callers may rely on the the ECDSA signature for non-repudiation. Without validating the ECDSA signature, an actor with trusted KMS permissions to decrypt a message may also be able to encrypt messages
