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:
    function __processMessage$1(modules, message) {
        var config = modules.config, crypto = modules.crypto;
        if (!config.cipherKey)
            return message;
        try {
            return crypto.decrypt(message);
        }
        catch (e) {
            return message;
        }
    }
