WHY EXPLOITFIXER

ExploitFixer is the best anti-exploit security plugin for Bukkit / Spigot / Paper Minecraft servers. It blocks crash clients such as Jessica, Jigsaw, Ayakashi, LiquidBounce, SmogClient, YSK and even private ones that are not known for yet. We are prepared for the future of exploits and crashers.

The plugin is high-performance and has many features like protection for CustomPayload spam, oversized packets exploit, crash commands, invalid NBT and many more type of crashers.

Unlike other plugins, Its intelligent packet limiter ensures effective protection by analyzing packet information dynamically.

ANTI-EXPLOIT FEATURES IN DETAIL
High Performance: ExploitFixer uses its own packet listener library (HamsterAPI), achieving exceptional performance (unlike other plugins and libraries like ProtocolLib) while remaining compatible with other plugins, thus effectively mitigating exploits without compromising server efficiency.

Packet Exploit Fix: ExploitFixer fixes various packet exploits by intelligently limiting their size and rate, offering protection against both known and private exploits that could potentially crash Minecraft servers.

CustomPayload Fixes: By limiting the content and types of CustomPayload, ExploitFixer effectively fixes this common method for exploitation.

Commands Crash Fix: The plugin features a configurable list of commands prone to crashing the server, effectively blocking their execution to prevent crashes permanently.

Creative Items Fix: ExploitFixer fixes hacked creative items by reconstructing their data, preventing any exploits associated with these items through extensive customization, including an item blacklist.

Signs Crasher Fix: ExploitFixer blocks the creation of invalid signs to fix crasher clients from using this vulnerability.

Lectern Crasher Fix: ExploitFixer blocks invalid interaction while on a lectern menu to prevent the server from crashing.

Map Label Crasher Fix: ExploitFixer disables labels from maps so players can't make zones that can crash players permanently because of too many maps with too many label entities.

Invalid Inventory Slot Fix: ExploitFixer blocks invalid slots interactions with any inventory so the server does not crash in the process.

NBT Crasher Fix: ExploitFixer blocks any item from having too many NBT tags which can cause the server to crash when a crasher client sends too many of this tags inside a packet.
