A critical vulnerability in Axelar Network allowed attackers to force validators to miss votes by crafting transactions with excessive logs that exceed Tendermint's 1MB RPC request limit, leading to automatic Chain Maintainer deregistration and potential halt of cross-chain operations. The vulnerability has been patched via governance proposal 256 disabling the auto-deregistration mechanism.
