Arbitrum Developers announced in a post on the X platform that Arbitrum Nitro and all Arbitrum chains are not affected by CVE-2025-24883. Arbitrum Nitro is based on go-ethereum, so it is not affected by this vulnerability. Any Arbitrum Nitro node operator of the Arbitrum chain does not need to take any action. However, it is strongly recommended that node operators update their nodes with the latest stable version to ensure that they benefit from the new features and bug fixes released.
