InventoryGui <=1.6.5: Item Dup via GuiStorageElement & Bundle
CVE-2025-62784 Published on October 27, 2025
InventoryGui allows item duplication in GUIs which use GuiStorageElement
InventoryGui is a library for creating chest GUIs for Bukkit/Spigot plugins. Versions before 1.6.5 contain a vulnerability where any plugin using a GUI with the GuiStorageElement and allows taking out items out of that element can allow item duplication when the experimental Bundle item feature is enabled on the server. The vulnerability is resolved in version 1.6.5.
Weakness Type
Improper Enforcement of a Single, Unique Action
The software requires that an actor should only be able to perform an action once, or to have only one unique action, but the software does not enforce or improperly enforces this restriction. In various applications, a user is only expected to perform a certain action once, such as voting, requesting a refund, or making a purchase. When this restriction is not enforced, sometimes this can have security implications. For example, in a voting application, an attacker could attempt to "stuff the ballot box" by voting multiple times. If these votes are counted separately, then the attacker could directly affect who wins the vote. This could have significant business impact depending on the purpose of the software.
