CVE-2024-58131Public exploitNetwork attack vector

Transaction hang via peer-controlled sealing delay

Published Apr 6, 2025 · Updated Apr 7, 2025

Incorrect transaction-pool synchronization in FISCO BCOS 3.11.0 allows remote attackers to hang blockchain transactions through a malicious node. The PBFT transaction flow accepts a peer node's excessive min_seal_time value as the network-wide sealing delay instead of enforcing a chain-agreed limit. The attacker must join the permissioned network with a modified node; an extreme value prevents legitimate transactions from returning execution results.
