Thirdweb Tackles Security Flaw in Web3 Library Impacting its Smart Contracts

In Brief

Thirdweb discovered a significant security vulnerability in a common open-source library widely used in the web3 industry for smart contracts.

Thirdweb Addresses Security Flaw in Web3 Library Affecting Smart Contracts

Web3 development platform Thirdweb recently became aware of a critical security vulnerability in a widely used open-source library on November 20th, 2023. The discovery has significant implications for numerous smart contracts within the web3 ecosystem, including some of Thirdweb’s own pre-built contracts.

The vulnerability affects various pre-built contracts like DropERC20, ERC721, ERC1155 and AirdropERC20. While Thirdweb’s investigation so far indicates no exploitation in their contracts, they have issued an urgent call to action for smart contract owners.

Smart contract owners who used Thirdweb’s dashboard or SDKs to deploy contracts before November 22nd, 2023, are advised to follow specific mitigation steps to prevent potential exploitation. These steps, which vary based on the contract’s nature, generally involve locking the contract, taking a snapshot, and migrating to a new contract.

Guidance for Thirdweb Smart Contract Owners

Thirdweb and its security partners have developed a tool to assist contract owners in determining and performing necessary mitigation steps. This tool, along with a detailed guide, is available on Thirdweb’s blog.

Upon learning of the vulnerability, Thirdweb’s security team, in collaboration with audit partners, investigated the issue and implemented a fix for all impacted contracts created after November 22nd, 2023. Contracts deployed after this date using the latest version do not suffer from this vulnerability.

In response to this incident, Thirdweb is increasing its investment in security measures.

This includes doubling bug bounty payouts and implementing stricter auditing processes. Thirdweb pledged to cover the gas fees for contract mitigations. Additionally, the platform has advised users to revoke approvals on Thirdweb contracts as a precautionary measure.

Looking forward, Thirdweb aims to enhance security protocols and create a robust environment for web3 developers. the platform have also reached out to the maintainers of the affected library and other potentially impacted teams to share their findings and mitigation strategies.

This incident underscores the importance of vigilant security measures in the rapidly evolving web3 landscape. Thirdweb’s proactive approach and transparent communication aim to ensure the safety and resilience of the web3 community.
