Calculating the previous pool's 'cumulativeRewardFactor' from the current pool incorrectly calculates the reward.

Lines of code Vulnerability details Impact When we updated a transcoder with rewards and then try to update a transcoder with fees, it incorrectly calculates the reward generated in the current round for that transcoder, which also incorrectly calculates the previous pool's cumulativeRewardFactor...

Read-only reentrancy is possible

Lines of code Vulnerability details Impact The agToken might be minted wrongly as rewards due to the reentrancy attack. Proof of Concept There are redeem/swap logics in the transmuter contract and all functions don't have a nonReentrant modifier. So the typical reentrancy attack is possible durin...

Amount of project token minted to beneficiary by JBXBuybackDelegate._mint function is not checked against an expected minimum number of project tokens to be minted to such beneficiary

Lines of code Vulnerability details Impact Calling the following JBPayoutRedemptionPaymentTerminal31.pay function executes fundingCycle, tokenCount, delegateAllocations, memo = store.recordPaymentFrompayer, bundledAmount, projectId, baseWeightCurrency, beneficiary, memo, metadata. File:...

Malicious user can Mint infinite amount of project tokens as anyone can call payParams function through malicious input and set the _tokenCount .

Lines of code Vulnerability details Impact Malicious user can Mint infinite amount of project tokens as anyone can call payParams function through malicious input and set the tokenCount. The payparams function calculates the tokenCount variable which refers to the amount of token to be minted or...

didPay() front-running

Lines of code Vulnerability details Impact The minting flow of tokens in JBXBuybackDelegate is divided into separate external functions: payParams and didPay. The didPay function can only be called by jbxTerminal, while payParams can be called by anyone without restrictions. The payParams functio...

MALICIOUS USER CAN USE LOCKED ETH OF THE CONTRACT TO MINT HIGHER NUMBER OF TOKENS OR SWAP AND RECIEVE MORE TOKENS THAN HE IS ELIGIBLE

Lines of code Vulnerability details Impact In the JBXBuybackDelegate contract, the terminal token is considered to be ETH as of now according to documentation. Hence both the mint and swap functionality uses the data.amount.value as the ETH amount for new token minting or swapping. In the...

Always mint 1 wei when _data.preferClaimedTokens is false

Unrestricted Token Transfer and Minting

Lines of code Vulnerability details Impact An attacker could exploit this vulnerability to mint an unlimited number of tokens, potentially devaluing the token and manipulating the market. Proof of Concept: Proof of Concept --The contract allows anyone to call the onTokenTransfer function without...

Positions can be created to mint unlimited tokens and still run off with the provided collateral.

Lines of code Vulnerability details Impact Brief Introduction A compromised position can be used to mint tokens up to the limit. The attacker can also withdraw this collateral. Hence, the attacker can mint tokens against his collateral and withdraw his collateral at the same time. Explanation...

An attacker can mint himself many tokens for free by cloning a position and adjusting its price

Lines of code Vulnerability details Impact A malicious attacker can mint himself the max limit amount of tokens of any position for free, by cloning a position and manipulating its price. Proof of Concept Steps overview: 1. a The attacker clones an existing position 2. b The attacker sets the pri...

[H-01] RETH oracle manipulation allows attacker to steal funds

Lines of code Vulnerability details Impact The Asymmetry SafEth protocol aims to help diversify and decentralize liquid staking derivatives, exchanging ether staked in the protocol for staked ether derivative tokens based on some relative weighting. A function exposed by these derivative wrapper...

Owner is able to mint 1 token more than 1000 prelaunch tokens due to wrong equality check

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. Owner is able to mint 1 token more than 1000 prelaunch tokens due to wrong check here Proof of Concept Provide direct links to all referenced code in GitHub. Add screenshots, logs, or any other relevant...

Potential Risk of Accidentally Minting Tokens to Incorrect Accounts

Lines of code Vulnerability details Impact 1. the Intended recipient of the tokens might not receive them, which could lead to a loss of funds or a delay in the intended use of the tokens 2. incorrect account holder could receive the tokens by mistake, leading to a discrepancy in the total token...

Users can lose funds due to stuck NFT's

Lines of code Vulnerability details Impact If msg.sender is a contract could also be smart contract wallet that does not implement the onERC721Received method, in the current implementation of fuse Namespace.sol && mint Bio.sol, the tx will still be successful, and the token will be minted. In th...

Price manipulation attack

Lines of code Vulnerability details Impact The PriceFeed.sol was marked OOS but I believe this to be a valid issue. If the chainlink feed fails which is does from time to time, the Tellor price feed takes over no matter what the delta is compared to the chainlink price. This is an issue because t...

Upgraded Q -> 3 from #648 [1675725284542]

Judge has assessed an item in Issue 648 as 3 risk. The relevant finding follows: 1. Incorrect Minter Address Validation in Mint Function Link : Summary: The mint function in the RabbitHoleReceipt contract does not correctly check the msg.sender address for minter permissions. The onlyMinter...

User can open position without depositing tokens

Lines of code Vulnerability details Impact User can mint long/short tokens without depositing anything. This is because the function on LN 172 doesn't check the contents of the returned data from the function, and the function doesn't verify that the contract has indeed received the expected...

Unchecked Token Minting: A Critical Vulnerability in Timeswap V2 Token Contract

Lines of code Vulnerability details Impact It allows an attacker to mint new tokens without proper checks and validations, which can result in an inflation of the total supply of tokens and a loss of funds for the contract's owner or users. The contract's "mint" function allows the attacker to mi...

Centralization Risks, Rug pull vectors

Lines of code Vulnerability details Impact Owner can mint or burn unlimited tokens, functions can be used to rug pull the project. Proof of Concept Although owner role is supposedly not malicious, if owner's wallet keys are compromised, an attacker could rug the project. Based on the fact that we...

unsafe transfer/TransferFrom breaks functionality of Collateral.sol

Lines of code Vulnerability details Description The ERC20 specification does not demand implementations to revert when the transfer and transferFrom functions fail. They may use the return value to signal the success code. Some tokens, like ZRX, indeed don't revert. In Collateral deposit and...
