Wrong authorization for CToken._setNameAndSymbol

Lines of code Vulnerability details Impact Anyone can change a CToken's name and symbol because of a wrong admin check: This will not only be very confusing for CToken holders but also allows many phishing attacks that will lead to loss of funds. For example, a victim holding both cWBTC and cUSDC...

CVE-2022-24787

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. In version 0.3.1 and prior, bytestrings can have dirty bytes in them, resulting in the word-for-word comparisons giving incorrect results. Even without dirty nonzero bytes, two bytestrings can compare to equal if one en...

System could be wrapped and made useless without contract whitelisting

Lines of code Vulnerability details Impact Anyone could create a contract or a contract factory "PAL Locker" with a fonction to deposit PAL tokens through a contract, lock them and delegate the voting power to the contract owner. Then, the ownership of this contract could be sold. By doing so,...

use of transfer() instead of call() to send eth

Lines of code Vulnerability details Impact Use of transfer might render ETH impossible to withdraw becuase after istanbul hardfork , there is increases in the gas cost of the SLOAD operation and therefore breaks some existing smart contracts.Those contracts will break because their fallback...

Incorrect implementation of the _startBridge function in CBridgeFacet

Lines of code Vulnerability details Impact The startBridge function in CBridgeFacet is to bridge the tokens to CBridge by calling the sendNative or send function on the bridge contract. However, when calling the sendNative function, no native token is sent to the bridge. The sendNative call alway...
