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