XRP Ledger Hotfix Closes Four Paths Used in Validator Manifest Flood

The XRP Ledger has released a hotfix called xrpld 3.2.1 to address an issue where excessive validator manifests were causing strain on its peer-to-peer infrastructure.

The problem occurred on July 31 when some nodes accepted, stored, and rebroadcasted unlimited numbers of untrusted manifest batches, leading to pressure on memory, bandwidth, storage, and processing capacity.

However, despite the disruption, the XRP Ledger continued to close ledgers normally, showing that consensus remained active while individual servers faced abnormal data pressure.

The new version introduces limits designed to prevent unknown validator data from consuming excessive resources. It rejects oversized manifests before decoding begins, discards incoming batches containing excessive numbers of untrusted manifests, and limits the bulk manifest greeting exchanged when nodes establish new peer connections.
