According to PANews, Arbitrum developers have announced on the X platform that Arbitrum Nitro and all Arbitrum chains are not impacted by the CVE-2025-24883 vulnerability. Arbitrum Nitro is based on go-ethereum, which makes it immune to this issue. Consequently, operators of Arbitrum Nitro nodes on any Arbitrum chain do not need to take any action. However, it is strongly recommended that node operators update to the latest stable version to benefit from newly released features and bug fixes.
