EufoniaSecurity 1.0.3

Security Fixes

Fixed: Container Merge Bypass

The previous fix in 1.0.2 for the double chest exploit had edge cases where players could still bypass locks by placing containers next to locked ones. This happened because:

• Some container types had null block groups, allowing the group comparison to fail
• The detection logic wasn't robust enough for all container variants

Now fixed: The plugin now uses multiple layers of detection to prevent container merging:

• Checks block groups AND block ID patterns to detect mergeable containers
• Handles all container variants correctly (Chest, ChestConnectedLeft, etc.)
• More robust world access with multiple fallback strategies
• Early performance optimization to only check connectable blocks

Players can no longer place any mergeable container (chest, barrel, etc.) next to a locked container under any circumstances. The fix is now bulletproof.

Configuration

New: Optional Support Block Protection

Support block protection (preventing breaking blocks under locked containers) is now configurable.

New config option: ProtectSupportBlockEnabled (default: true)

• When true: Blocks directly below locked containers are protected (existing behavior)
• When false: Players can break blocks under locked containers

This allows server admins to choose whether to enforce support block protection based on their server's needs. The default value maintains the current secure behavior.
