Fallout 76 exploits

Known active exploits

 * Infinite storage: The artillery piece can be used to bypassing the My stash box storage limits by placing arbitrary items into the box and storing the artillery piece.
 * Unlocked items: Items that are not yet owned by the player can be created by the C.A.M.P. if the player is already able to create any variant of the item in that construction level. The player simply needs to place the item that can already be created, store it, and then go to the Stored tab and place it back down as a different variant.
 * Infinite carry: Armor that have the "pocketed" attribute can be equipped and de-equipped very rapidly to gradually lower the player's carrying weight until it becomes negative, giving the player an unlimited carrying weight for the rest of that server session.
 * Power armor duplication: Exiting the armor within a C.A.M.P. and disconnecting the network connection
 * Power armor duplication: Exiting the armor while dropping a "portable fuel tank" can cause a race condition.

Historical exploits

 * Infinite grenades and XP: The Home Defense perk can be used by the player to repeated disarm certain grenade traps to yield large numbers of fragmentation grenades and XP. (fixed by Fallout 76 patch 1.0.2.0)
 * Infinite items: The artillery piece can be used to duplicate arbitrary items by placing them into the box of an artillery piece belonging to another player prior to that player logging out. (possibly fixed by the service outage that followed Fallout 76 patch 1.0.2.0)
