      The Bug:

      You can fill composters in adventure mode.

      Steps to Reproduce:

      • Place down a composter and obtain some seeds.
      • Switch into adventure mode and attempt to fill the composter.
      • Take note as to whether or not you can fill composters in adventure mode.

      Observed Behavior:

      You can fill composters in adventure mode.

      Expected Behavior:

      You would not be able to fill composters in adventure mode.

      Code Analysis:

      Code analysis by Avoma can be found below.

      The following is based on a decompiled version of Minecraft 1.18.1 using MCP-Reborn.

      public class ComposterBlock extends Block implements WorldlyContainerHolder {
         public InteractionResult use(BlockState $bs, Level $l, BlockPos $bp, Player $p, InteractionHand $ih, BlockHitResult $bhr) {
            int i = $bs.getValue(LEVEL);
            ItemStack itemstack = $p.getItemInHand($ih);
            if (i < 8 && COMPOSTABLES.containsKey(itemstack.getItem())) {
               if (i < 7 && !$l.isClientSide) {
                  BlockState blockstate = addItem($bs, $l, $bp, itemstack);
                  $l.levelEvent(1500, $bp, $bs != blockstate ? 1 : 0);
                  if (!$p.getAbilities().instabuild) {

      If we look at the above class, we can see that no checks are carried out to see what abilities the player possesses when filling a composter. The only checks that are in place are to see whether the level of the composter is less than 8, and if the item held by the player is compostable. This is evident through the following line of code:

      if (i < 8 && COMPOSTABLES.containsKey(itemstack.getItem()))

      Potential Fix:

      Simply adding a line of code that checks what abilities the player possesses before filling a composter, should resolve this problem. The following line of code could be used in order to fix this:
