CWE: CWE-331 \u2014 Insufficient Entropy
The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

Code:
    AesCbcCryptor.prototype.getKey = function () {
        var sha = (0, crypto_1.createHash)('sha256');
        sha.update(Buffer.from(this.cipherKey, 'utf8'));
        return Buffer.from(sha.digest());
    };
