How to fix?

Upgrade openssl-encrypt to version 1.4.0 or higher.

Overview

openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files

Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity via the CamelliaCipher process when the PYTEST_CURRENT_TEST environment variable is set. An attacker can bypass integrity protection on encrypted data by setting this environment variable to disable HMAC tag generation and verification, resulting in unauthenticated ciphertext.
