+## L-1 draw can be started with `redraw()` instead of `startDraw()`
+
+By transfering the raffled NFT to the contract manually a owner can start the raffle with `redraw()` instead of `startDraw()`.
+
+### Impact
+This omits sending the `SetupDraw` event which could affect listeners to the protocol. It also breaks the intended usage flow.
+
+### Proof of Concept
+PoC test in `VRFNFTRandomDraw.t.sol`:
+
+```javascript
+   function test_FullDrawingStartWithRedraw() public {
+        address winner = address(0x1337);
+        vm.label(winner, "winner");
+
+        vm.startPrank(winner);
+        for (uint256 tokensCount = 0; tokensCount < 10; tokensCount++) {
+            drawingNFT.mint();
+        }
+        vm.stopPrank();
+
+        vm.startPrank(admin);
+        targetNFT.mint();        
+
+        address consumerAddress = factory.makeNewDraw(
+            IVRFNFTRandomDraw.Settings({
+                token: address(targetNFT),
+                tokenId: 0,
+                drawingToken: address(drawingNFT),
+                drawingTokenStartId: 0,
+                drawingTokenEndId: 10,
+                drawBufferTime: 1 hours,
+                recoverTimelock: block.timestamp + 1 weeks,
+                keyHash: bytes32(
+                    0x79d3d8832d904592c0bf9818b621522c988bb8b0c05cdc3b15aea1b6e8db0c15
+                ),
+                subscriptionId: subscriptionId
+            })
+        );
+        vm.label(consumerAddress, "drawing instance");
+
+        mockCoordinator.addConsumer(subscriptionId, consumerAddress);
+        mockCoordinator.fundSubscription(subscriptionId, 100 ether);
+
+        VRFNFTRandomDraw drawing = VRFNFTRandomDraw(consumerAddress);
+        targetNFT.setApprovalForAll(consumerAddress, true);
+
+        // move nft to contract manually
+        targetNFT.transferFrom(admin, consumerAddress, 0); 
+        // start with redraw instead of startDraw()
+        uint256 drawingId = drawing.redraw();
+
+        mockCoordinator.fulfillRandomWords(drawingId, consumerAddress);
+        vm.stopPrank();
+        
+        vm.prank(winner);
+        drawing.winnerClaimNFT();
+        assertEq(targetNFT.balanceOf(winner), 1);
+        assertEq(targetNFT.balanceOf(consumerAddress), 0); 
+    }
+```
+
+### Tools Used
+vs code, forge
+
+### Recommended Mitigation Steps
+before doing a `redraw()`, verify that `currentChainlinkRequestId` is not empty. Then has to have been started before (through `startDraw()`).

+## L-4 anyone can call `initialize()`
+
+There is no validation that it's the factory that created the contract that is calling `initialize()`. This could be achieved by adding immutable value with the creator in the constructor.  
+
+# non-crit
+
+## NC-1 unreachable code #1
+
+https://github.com/code-423n4/2022-12-forgeries/blob/main/src/VRFNFTRandomDraw.sol#L144-L146
+
+In `_requestRoll()`:
+```javascript
+141:    function _requestRoll() internal {
+142:        // Chainlink request cannot be currently in flight.
+143:        // Request is cleared in re-roll if conditions are correct.
+144:        if (request.currentChainlinkRequestId != 0) { // can never be !=0
+145:            revert REQUEST_IN_FLIGHT();
+146:        }
+```
+
+This can never happen. `_requestRoll()` is called from two places:
+
+`startDraw()` which checks that `currentChainlinkRequestId != 0` before going into `_requestRoll()`:
+```javascript
+173:    function startDraw() external onlyOwner returns (uint256) {
+174:        // Only can be called on first drawing
+175:        if (request.currentChainlinkRequestId != 0) {
+176:            revert REQUEST_IN_FLIGHT();
+177:        }
+
+...
+
+182:        // Request initial roll
+183:        _requestRoll();
+```
+
+and in `redraw()` which just before does `delete request` which resets `currentChainlinkRequestId` to `0`:
+```javascript
+203:    function redraw() external onlyOwner returns (uint256) {
+204:        if (request.drawTimelock >= block.timestamp) {
+205:            revert TOO_SOON_TO_REDRAW();
+206:        }
+207:
+208:        // Reset request
+209:        delete request;
+210:
+211:        // Re-roll
+212:        _requestRoll();
+```
+
+## NC-2 unreachable code #2
+
+https://github.com/code-423n4/2022-12-forgeries/blob/main/src/VRFNFTRandomDraw.sol#L149-L156
+
+In `_requestRoll()`:
+```javascript
+203:        if (
+204:            request.hasChosenRandomNumber &&
+205:            // Draw timelock not yet used
+206:            request.drawTimelock != 0 &&
+207:            request.drawTimelock > block.timestamp
+208:        ) {
+209:            revert STILL_IN_WAITING_PERIOD_BEFORE_REDRAWING();
+210:        }
+```
+
+This can never happen. `_requestRoll()` is called from these two places:
+
+`startDraw()`, already has a check for that `hasChosenRandomNumber` is `0`:
+
+```javascript
+173:    function startDraw() external onlyOwner returns (uint256) {
+174:        // Only can be called on first drawing
+175:        if (request.currentChainlinkRequestId != 0) {
+176:            revert REQUEST_IN_FLIGHT();
+177:        }
+
+...
+
+182:        // Request initial roll
+183:        _requestRoll();
+```
+
+and in `redraw()` `request.drawTimelock` is checked already and it then does `delete request` which resets `currentChainlinkRequestId` to `0`:
+```javascript
+203:    function redraw() external onlyOwner returns (uint256) {
+204:        if (request.drawTimelock >= block.timestamp) {
+205:            revert TOO_SOON_TO_REDRAW();
+206:        }
+207:
+208:        // Reset request
+209:        delete request;
+210:
+211:        // Re-roll
+212:        _requestRoll();
+```
