Multiple re-entrancy issues allowing stealing of funds and bypassing protocol mint limits

Lines of code Vulnerability details Impact Multiple re-entrancy issues exist in the codebase, that break core functionality and allow stealing of user funds. In AuctionDemo.sol contract re-entrancy in cancelBid and cancelAllBids allows stealing of user funds. There are multiple attack surfaces,...

[H-02] The Ocean contract and the onERC721Received function is vulnerable to read-only re-entrancy

Lines of code Vulnerability details Impact The contract.function called Ocean.onERC721Received is vulnerable to read-only re-entrancy. The read-only re-entrancy is possible if the contract function is called externally from another contract. What follows are the functions that are traversed throu...

High risk in integrating Ocean with Curve TriCrypto pool on Arbitrum

Lines of code Vulnerability details Impact The Curve TriCrypto adapter contract enables swapping, adding liquidity, and removing liquidity for the USDT-WBTC-ETH pool on Arbitrum. However, this pool has been flagged for potential exploit risks. Curve Finance issued a warning: This pool might be at...

[M-17] Reentrancy in the BranchBridgeAgent contract

Lines of code Vulnerability details Impact In a Re-entrancy attack, a malicious contract calls back into the calling contract before the first invocation of the function is finished. This may cause the different invocations of the function to interact in undesirable ways, especially in cases wher...

Vyper has incorrect re-entrancy lock when key is empty string

Impact Locks of the type @nonreentrant"" or @nonreentrant'' do not produce reentrancy checks at runtime. Vyper @nonreentrant"" unprotected @external def bar: pass @nonreentrant"lock" protected @external def foo: pass Patches Patched in 3605 Workarounds The lock name should be a non-empty string...

Vyper has incorrectly allocated named re-entrancy locks

Impact In versions 0.2.15, 0.2.16 and 0.3.0, named re-entrancy locks are allocated incorrectly. Each function using a named re-entrancy lock gets a unique lock regardless of the key, allowing cross-function re-entrancy in contracts compiled with the susceptible versions. A specific set of...

Incorrect Re-Entrancy Lock Allocation

vyper is vulnerable to Incorrect Re-Entrancy Lock Allocation. The allocation of named re-entrancy locks is flawed, which makes cross-function re-entrancy possible in contracts, because each function employing a named re-entrancy lock receives a distinct lock independent of the key under a specifi...

CVE-2023-39363

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine EVM. In versions 0.2.15, 0.2.16 and 0.3.0, named re-entrancy locks are allocated incorrectly. Each function using a named re-entrancy lock gets a unique lock regardless of the key, allowing cross-function re-entrancy in...

ARBTriCryptoOracle is prone to manipulation

Lines of code Vulnerability details Impact ARBTriCryptoOracle is used to determine price of LP token of tricrypto USDT, WBTC, WETH on arbitrum. This pool is susceptible to re-entrancy due to bug in vyper 0.2.15. and hence getvirtualprice can be manipulated which is used for pricing LP tokens. Pro...
