Cosine: If a project uses the Thirdweb platform to develop smart contracts, it may be affected by its security vulnerabilities

Yu Xian, the founder of SlowMist, posted on the Users' assets may also be affected. You can check according to official recommendations. Although the official said no real attacks have been found, I am afraid there will be one soon. After all, open source diff analysis is relatively easy." Earlier today, the Web3 developer platform Thirdweb posted on the X platform that the team discovered security vulnerabilities in open source libraries commonly used in the Web3 industry at 10:00 on November 21, Beijing time. This affects various smart contracts in the Web3 ecosystem, including some of Thirdweb’s pre-built smart contracts. Based on investigations to date, this vulnerability has not yet been exploited in ThirdWeb smart contracts. However, smart contract owners must take mitigation measures for certain pre-built contracts created on ThirdWeb before 11:00 Beijing time on November 23. Affected pre-built contracts include, but are not limited to, DropERC20, ERC721, ERC1155 (all versions), and AirdropERC20.
