Bundle Crash Fix is a server side security plugin for the Velocity proxy that helps stop malicious players from abusing the bundle crashing method against a Minecraft server. Designed for Java Edition networks using Velocity, it addresses the packet handling issue behind this type of disruption and helps keep player connections more stable.
The plugin supports Minecraft 1.21.2 through 1.21.4 and focuses on lightweight protection, with improved logging included in version 1.3. At BoxToPlay, we recommend it for proxy based networks seeking an extra defensive layer against targeted crash attempts.
