A vulnerability in the Paradigm Reth client caused a brief outage of multiple Ethereum nodes

Jinse Finance reported that Paradigm's Ethereum Reth execution client encountered an error on Tuesday, causing nodes to stall. Paradigm CTO Konstantopoulos shared a set of commands to restore the nodes, but the root cause of the vulnerability has not yet been identified. According to a post on Paradigm's GitHub page, the vulnerability occurred at block height 2327426 and affected Ethereum mainnet versions 1.6.0 and 1.4.8. Although Konstantopoulos shared a set of commands for operators to restore Reth nodes, Paradigm is still investigating the root cause of the vulnerability. Reth is an Ethereum execution layer client developed by Paradigm using the Rust programming language, focusing on high performance and modularity.
