How to fix?
Upgrade @aws-crypto/decrypt-node to version 2.2.0, 1.9.0 or higher.
Overview
@aws-crypto/decrypt-node is an AWS Encryption SDK for Javascript and Node.js
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, but 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.
