Balancer released a solution to a non-critical issue in January: the pool factory will be redeployed in the next few days

Balancer released a fix for a non-critical issue disclosed in early January that will be fully resolved (with minor changes) by redeploying Pool factories in the coming days. Balancer said the issue disclosed on Jan. 6 involved the previously mentioned read-only reentrancy issue, which could be used to manipulate prices in some specific nested pools by using stale data. The vulnerability has not yet been exploited, most pools are unaffected, and almost all liquidity has been removed from relevant pools by LPs. On January 6, Balancer tweeted, “The protocol fees of some Balancer pools have been set to 0 to avoid a problem that will be publicly disclosed, and the problem has been alleviated.” Subsequently, Balancer urged some pools’ LPs to withdraw liquidity as soon as possible nature, because the emergency DAO cannot alleviate this related problem. The pools that need to withdraw liquidity include DOLA / bb-a-USD on the Ethereum mainnet (locked amount of $3.6 million at the time), bb-am-USD/miMATIC on Polygon (locked amount of $9,000), Beethoven X on Optimism (powered by Balancer) It's MAI life ($1.1 million lockup) and Smells Like Spartan Spirit ($90,000 lockup), Beethoven X's Tenacious Dollar on Fantom ($1.6 million lockup).
