Improper Verification of Cryptographic Signature

aws-encryption-sdk is an AWS Encryption SDK implementation for Python

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

How to fix Improper Verification of Cryptographic Signature?

Upgrade aws-encryption-sdk to version 2.2.0, 1.9.0 or higher.
