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.encryptFileData = function (data) {
            return __awaiter(this, void 0, void 0, function () {
                var key, iv;
                var _a;
                return __generator(this, function (_b) {
                    switch (_b.label) {
                        case 0: return [4 /*yield*/, this.getKey()];
                        case 1:
                            key = _b.sent();
                            iv = this.getIv();
                            _a = {};
                            return [4 /*yield*/, crypto.subtle.encrypt({ name: this.algo, iv: iv }, key, data)];
                        case 2: return [2 /*return*/, (_a.data = _b.sent(),
                                _a.metadata = iv,
                                _a)];
